I am trying to build an app, with fastapi. I was trying to use keycloak for authentication part,
from fastapi_keycloak import FastAPIKeycloak, OIDCUser
app = FastAPI()
idp = FastAPIKeycloak(
server_url="https://auth.some-domain.com/auth",
client_id="some-client",
client_secret="some-client-secret",
admin_client_secret="admin-cli-secret",
realm="some-realm-name",
callback_uri="http://localhost:8081/callback"
)
idp.add_swagger_config(app)
I am using version 20.0 and someone recommended to not use http:// when providing server url.
I followed this process for integration https://fastapi-keycloak.code-specialist.com/#apppy as per this documentation. Now when I am giving my server url starting with http:// it shows throws an error, i.e. MissingSchema: Invalid URL 'None': No scheme supplied. Perhaps you meant http://None? and without http://
InvalidSchema(f"No connection adapters were found for {url!r}")
requests.exceptions.InvalidSchema: No connection adapters were found for this is the result.
Can someone please look into this and help me out.
Thank you InvalidSchema(f"No connection adapters were found for {url!r}")
requests.exceptions.InvalidSchema: No connection adapters were found for
FastAPi not support v20.0, it supports v16.1.x(latest version v16.1.1)
So you can't using with v20.0
I tested this docker compose and app.py
This is access roles API to FastAPI
http://localhost:8081/roles
I just started using Postman. I had this error "Error: socket hang up" when I was executing a collection runner. I've read a few post regarding socket hang up and it mention about sending a request and there's no response from the server side and probably timeout. How do I extend the length of time of the request in Postman Collection Runner?
For me it was because my application was switched to https and my postman requests still had http in them. Changing postman to https fixed it.
Socket hang up, error is port related error. I am sharing my experience. When you use same port for connecting database, which port is already in use for other service, then "Socket Hang up" error comes out.
eg:- port 6455 is dedicated port for some other service or connection. You cannot use same port (6455) for making a database connection on same server.
Sometimes, this error rises when a client waits for a response for a very long time. This can be resolved using the 202 (Accepted) Http code. This basically means that you will tell the server to start the job you want it to do, and then, every some-time-period check if it has finished the job.
If you are the one who wrote the server, this is relatively easy to implement. If not, check the documentation of the server you're using.
Postman was giving "Could not get response" "Error: socket hang up".
I solved this problem by adding the Content-Length http header to my request
Are you using nodemon, or some other file-watcher? In my case, I was generating some local files, uploading them, then sending the URL back to my user. Unfortunately nodemon would see the "changes" to the project, and trigger a restart before a response was sent. I ignored the build directories from my file-watcher and solved this issue.
Here is the Nodemon readme on ignoring files: https://github.com/remy/nodemon#ignoring-files
I have just faced the same problem and I fixed it by close my VPN. So I guess that's a network agent problem. You can check if you have some network proxy is on.
this happaned when client wait for response for long time
try to sync your API requests from postman
then make login post and your are done
I defined Authenticate method to generate a token and mentioned its return type as nullable string as:
public string? Authenticate(string username, string password)
{
if(!users.Any(u => u.Key==username && u.Value == password))
{
return null;
}
var tokenHandler = new JwtSecurityTokenHandler();
var tokenKey = Encoding.ASCII.GetBytes(key);
var tokenDescriptor = new SecurityTokenDescriptor()
{
Subject = new ClaimsIdentity(new Claim[]
{
new Claim(ClaimTypes.Name, username)
}),
Expires = DateTime.UtcNow.AddHours(1),
SigningCredentials = new SigningCredentials(new
SymmetricSecurityKey(tokenKey),
SecurityAlgorithms.HmacSha256Signature)
};
var token = tokenHandler.CreateToken(tokenDescriptor);
return tokenHandler.WriteToken(token);
}
Changing nullable string to simply string fixed "Socket Hang Up" issue for me!
If Postman doesn't get response within a specified time it will throw the error "socket hang up".
I was doing something like below to achieve 60 minutes of delay between each scenario in a collection:
get https://postman-echo.com/delay/10
pre request script :-
setTimeout(function(){}, [50000]);
I reduced time duration to 30 seconds:
setTimeout(function(){}, [20000]);
After that I stopped getting this error.
I solved this problem with disconnection my vpn. you should check if there is vpn connected.
What helped for me was replacing 'localhost' in the url to http://127.0.0.1 or whatever other address your local machine has assigned localhost to.
Socket hang up error could be due to the wrong URL of the API you are trying to access in the postman. please check the URL once carefully.
It's possible there are 2 things, happening at the same time.
The url contains a port which is not commonly used AND
you are using a VPN or proxy that does not support that port.
I had this problem. My server port was 45860 and I was using pSiphon anti-filter VPN. In that condition my Postman reported "connection hang-up" only when server's reply was an error with status codes bigger than 0. (It was fine when some text was returning from server with no error code.)
When I changed my web service port to 8080 on my server, WOW, it worked! even though pSiphon VPN was connected.
Following on Abhay's answer: double check the scheme. A server that is secured may disconnect if you call an https endpoint with http.
This happened to me while debugging an ASP.NET Core API running on localhost using the local cert. Took me a while to figure out since it was inside a Postman environment and also it was a Monday.
In my case, adding in the header the "Content-length" parameter did the job.
My environment is
Mac:
[Terminal command: sw_vers]
ProductName: macOS
ProductVersion: 12.0.1. (Monterey)
BuildVersion: 21A559
mysql:
[Terminal command: mysql --version]
Ver 8.0.27 for macos11.6 on x86_64 (Homebrew)
Apache:
[Terminal command: httpd -v]
Server version: Apache/2.4.48 (Unix)
Server built: Oct 1 2021 20:08:18.
*Laravel
[Terminal command: php artisan --version]
Laravel Framework 8.76.2
Postman
Version 9.1.5 (9.1.5)
socket hang up error can also occur due to backend API handling logic.
For example - I was trying to create an Nginx config file and restart the service by using the incoming API request body. This resulted in temporary disconnection of the Nginx service while handling the API request and resulted in socket hang up.
If you have tried all the steps mentioned in other comments, and still face the issue. I suggest you check the API handler code thoroughly.
I handled the above-mentioned example by calling the Nginx reset method with delay and a separate API to check the status of the prev reset request.
For me it was giving Socket Hung Up error only while running Collection Runner not with single request.
Adding a small delay (100-300ms) in the collection Runner solved issue for me.
In my case, I had to provide --ssl-client-key and --ssl-client-cert files to overcome these errors.
Great error, it is so general that for everyone something different helps.
In my case I was not able to fix it and what is really funny is fact that I am expecting to get multipart file on one endpoint. When I prepare request in postman I get "Error: socket hang up". If I change for other endpoint(even not existing) is exactly that same error. But when I call any endpoint without body that request works and after that all subsequent attempts works perfectly.
In my case this is purely postman issue. Any request using curl is never giving that error.
For me the issue was related to the mismatch of the http versions on the client and server.
Client was assuming http v2 while server (spring boot/ tomcat) in the case was http v1
When on the server I configured server to v2, the issue got resolved in a go.
In spring boot you can configure the http v2 as below:-
server.http2.enabled=true
Note - Also the scenario was related to using client auth mechanism (i.e. MTLS)
Without client auth/ MTLS it worked without issues but for client auth the version setting in spring boot was the important rescue point
"socket hang up" is proxy related issue. when we run same collection with the help of newman on jenkins then all test are passed.
change the proxy setting

I had the same issue: "Error: socket hang up" when sending a request to store a file and backend logs mentioned a timeout as you described. In my case I was using mongoDB and the real problem was my collection’s array capacity was full. When I cleared the documents in that collection the error was dismissed. Hope this will help someone who faces a similar scenario.
"Socket Hung Up" can be on-premise issue some time's, because, of bottle neck in %temp% folder, try to free up the "temp" folder and give a try
I fixed this issue by disabling Postman token header. Screenshot:
I face the same issue in when calling a SOAP API with POSTMAN
by adding the following data in the header my issue was fixed
Key:Content-Length
Value:<calculated when request is sent>
In my case, I was incorrectly using a port reserved for https version of my api.
For example, I was supposed to use https://localhost:6211, but I was using http://localhost:6211.
It is port related error. I was trying to hit the API with an invalid port.
if it helps to anybody... In my case, i just forgot to use json parser (const jsonParser = express.json();) to have access to json type of objects sending to the server from the client. Be careful, don't waste your time =)
This happened to me while I was learning ASP.NET Web API.
In my case it was because the SSL certificate verification.
I was using VS Code so I oversee about SSL certificate verification and it came with https protocol.
I solved this with testing my endpoints with http protocol.
Another approach can be just disabling the SSL certificate Verification on Postman Settings.
This error was coming for me since the request url is not correct --> here you can see my url does not contains : after http
The url I was using was : http//locahost:9090/someApi
Solution
adding a colon new url is http://localhost:9090/someApi
the socket error was not coming
This is just my case may be your case is totally different as mentioned in the other answers :)
This error is driving me nuts...
Situation:
I am trying to create a REST api and use a api-gateway proxy to access it. Proxy URL is HTTPS.
The deployment goes through fine. No errors reported in the logs. Worker assigned.
However when I try to access through browser get the "Uh-oh spaghettios! There's nothing here.".
Have tried all the usual things like making the https port dynamic using ${https.port} and using 0.0.0.0 instead of localhost in the http-listener config. But that does not help. Has this something to got to do with the proxy version ?
Any help or pointers will be great!
Make sure you follow Steps 2 from below link
Getting Started with Connectors
All,
Got the resolution. The problem was with the certificate chain. The keystore did not contain intermediate certificates. When added to the keystore the connectivity worked fine.
Only if Mulesoft provided correct errors or detailed logging, I would have saved lot of time over this.
Thanks for your inputs.
I set up an application with the Intuit Customer Account Data API and am running a Rails app using Aggcat gem (https://github.com/cloocher/aggcat). I had to replace my certificate and followed the instructions for OpenSSL found here. Under My Apps I uploaded the new public certificate and changed the settings on Aggcat to use the new private key file generated with it.
I can run client.scope(1) but when I try to run anything else (such as client.institutions) I get a bad request error (400). Any ideas what the problem could be? I've tried re-generating the certificate multiple times and no luck.
According IPP's site,
400 - Bad Request represents - If the URL or variables are not in the correct format this error will display.
Ref - https://developer.intuit.com/docs/0020_customeraccountdata/customer_account_data_api/0700_error_codes
I've not tried CAD calls using ruby but I use the sample JAVA app(IPP).
You can run the sample java app ( by configuring the devkit logger in debug mode) and capture the raw request/response and URL(and parameters) and compare the same which you're getting in your ruby example. That might help you to debug these issues.
Otherwise, you can also try the other two ruby examples which are available here-

I am using SQL Server CE 4.0 with WebApi on Windows Azure Websites. I have been successfully able to deploy SQL Server CE. The weird problem I am facing is that my site is able to log me in using the same DB but I am not able to use any of the controllers to fetch the data.
I am using same connection string for both. The only difference is that for logging in I am using WebSecurity as I have enabled OAuth on the site.
Can someone throw some light on how to debug and fix this issue? The error I am getting for the calls is
Format of the initialization string does not conform to specification
starting at index 0.
However the same string works for authentication, change password, adding OAuth connections etc.
Thanks in advance
I connected to the site using FTP. I was not giving the site name as domain name and it was denying me access earlier. On connecting, I got hold of the Web.config file and I found something interesting. While publishing the site, the web.config was modified to add another connectionstring with the name of context_DatabasePublish.
This string had following details connectionString="ContextName_DatabasePublish.ConnetionString" providerName="System.Data.SqlClient"
Also there was a new section called context added to the entityframework section of the config file with all the details for the context to use but again pointing to same connection string. The provider it is using is sql and not sqlce. I believe that is the reason it was failing.
I uploaded my normal config file and the site started working. I need to explore more on to why and how the new connection string got added. I will post the details in comments.
