i have a problem,
when i tried to Manage Nuget Packages VS2017 showed me this message:
[nuget.org] Unable to load the service index for source https://api.nuget.org/v3/index.json.
An error occurred while sending the request.
The underlying connection was closed: An unexpected error occurred on a send.
Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
Please can you help me to solve this problem??
I'm going crazy
Thank you
That is a bug in VS 2017. (I had the same problem). This has been fixed in VS version 15.1 . To fix this problem update your VS through vs_Community.exe installer (which you can download here).

I am developing a MERN stack application. My Node web server used to work fine. Recently however, whenever I start my Node server, I get the following error:
[1] Error: queryTxt ESERVFAIL cluster0.b4oyxi0.mongodb.net
[0] [HPM] Error occurred while proxying request localhost:3000/api/users/login to http://localhost:5000/ [ECONNRESET] (https://nodejs.org/api/errors.html#errors_common_system_errors)
[1] [nodemon] app crashed - waiting for file changes before starting...
What does this error mean and how can I fix it?
Not exactly sure what the error means. I encountered a similar error and the non +srv connection string did it for me.
To get one,
head out to your Atlas Dashboard under Database Deployment,
click Connect,
then choose Connect your application.
On the Node.js driver version, lower that to 2.2.12 or later.
This should give the connection string.
It's a DNS server issue. Try changing your DNS server in your network settings to any of these, or any other trusted one you know:
208.67.222.222
1.1.1.1
8.8.8.8
9.9.9.9
I'm working on a group project using teletype, but when one of my peers tries to connect to the portal I opened, they just get the error "Connecting to peer timed out". When I try and connect to the portal my peer created, the application says something similar.
I know this is more of a logistics question, but is there any way to fix this? I haven't really been able to find a solution.
We have moved our TFS data tier server to another machine. Everything was reconfigured and is working EXCEPT email alerts. Test emails are sent just fine. However, alerts are not happening. When I checked the event viewer, I'm seeing the following error:
ds:OLDSERVERINSTANCE db:Tfs_Configuration errors:-1 exception:System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
So, it appears that the email is still looking at the old database (which has been retired). Where/how can I change this?
In case anyone else runs into this scenario. The TFSJobAgent wasn't smart enough on reboot to recognize the data tier change. Doing the following worked:
1. Stop iis
2. Stop the TFSJobAgent
3. Start the TFSJobAgent
4. Start iis
Hy friends,
I have struggled with this problem all day long. I have asp .net 4.0 web application running on iis 7. It running well when not performing connectivity on database.
I am using sqlserver 2005. when i connect to server using the SqlClient it produces error as follows:
A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The wait operation timed out.)
but when i use sqloledb to connect to my remote database,then successfully connected. I would appreciate if anyone could give me some solution regarding to my problem.
Thank you.
I have been scratching my head since long now to get rid of following error message.
Warning: stream_socket_client() [function.stream-socket-client]: unable to connect to ssl://gateway.push.apple.com:2195 (Connection refused)
I have tried multiple times generating the correct certificate and made sure that project is signed with the correct bundle identifier.
I have also tried using testing script PHP(https://devforums.apple.com/message/50461) and Python (http://stackoverflow.com/questions/1052645/apple-pns-push-notification-services-sample-code) but both are giving same error message.
Could anyone please help me to know how to get rid of this error message?
Thanks.
Gotcha...Our firewall setup to not allow any other ports not listed in settings. Asked admin people to add it and it doesn't show this error message now....!! I have sent and message but didn't receive since last 5 minutes. I know that APNS messages are not guaranteed. Will wait for some more time. Hopefully it arrives.. :)
