i receive lot of :
[kuzzle networkError] : Error: Unable to connect to kuzzle server at 127.0.0.1:7512: Connection lost. (ws status=503)
since i start using apikey from createApikey, may it be related to a bad usage of the token ?
seems to happen after every successful query

Not sure if I'm missing anything.
I'm trying to create a local connection in order to create a new user in Oracle SQL developer 12c. (AVOIDING CDB connection)
After browsing for an hour, came across 2 methods.
Using connection type as "Local/Bequeath"
Throws following error (Status : Failure -Test failed: ORA-01017: invalid username/password; logon denied)
Using connection type as "Basic", Hostname as "localhost", Port as "1521", and Service name as "XEPDB1"
Throws following error (Status : Failure -Test failed: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor)
Thanks.
I am following IdentityServer4 quickstart and trying to migrate in memory data to my local SQL Server (not SQL express or LocalDB that came with VS). My connection string is:
#"Server=localhost,1434;Database=MyIDS;user id=tester_1;Password=tester_1;trusted_connection=yes;".
When I start my IdentityServer, it creates the enpty db, MyIDS, and then throw an exception with 2 inner exceptions:
Inner Exception 1:
SqlException: A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - An established connection was aborted by the software in your host machine.)
Inner Exception 2:
Win32Exception: An established connection was aborted by the software in your host machine.
Can anyone tell me what's going on here? Why a working connection always gets dropped?
localhost,1434 looks wrong, you don't need to provide the port 1434 and the commma should not be used either, it should be a colon in that case.
I typically use for local development:
server=.;Database=ASPIdentity;Trusted_Connection=True;
dot means localhost, if you use sqlexpress the connetion string would become
server=.\\sqlexpress;Database=ASPIdentity;Trusted_Connection=True;
I am having difficulty getting the gcloud sql proxy working on my local machine. I have gone through all the steps here however I am getting the following errors. It is unclear to me what is actually going wrong. Important things to note, I am not using a service account, I am authenticating with my own account through gcloud auth login and I am following the TCP sockets steps.

The most likely reason you are receiving this error message is because you are using a First Generation instance.
Proxy connectivity is only supported for Second Generation instances.
I am developing a C# MVC Web API which uses MongoDb as backend.I tried connecting to my mongodb database using
MongoClient mongoClient = new MongoClient(connectionString)
where connectionstring is in format : mongodb://Username:Password#hostname.eastus.cloudapp.azure.com
Mongo db is hosted in a virtual machine in Azure.I am able to connect to the database and all works good.But I am getting frequent exceptions:
"MongoDb.driver.MongoConnectionException".An exception occurred while
receivinf a message from server--->System.IO.IOException: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,......"
So after a bit of research I have learnt that Azure is killing idle connections and I have to set MaxConnectionIdleTime.
In order to set MaxConnectionIdleTime I decided to connect to Mongodb in the below way
var credential = MongoCredential.CreateCredential("dbname", "UserName", "Password");
var settings = new MongoClientSettings
{
Credentials = new[] { credential },
Server = new MongoServerAddress("HostName", 27017),
MaxConnectionIdleTime = new TimeSpan(0, 3, 0)
};
MongoClient mongoClient = new MongoClient(settings);
In this case I am using the same username,password combination given in the connection string which I used to connect before.
While trying to connect here I am getting inner Exception:
MongoDB.Driver.MongoAuthenticationException: "Unable to authenticate
using sasl protocol mechanism SCRAM-SHA-1".
"MongoDb.driver.MongoConnectionException".An exception occurred while receivinf a message from server--->System.IO.IOException: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,....
The reason behind this exception is when hosted in Azure,Azure tries to kill the idle connections but the C# driver is not aware of this.The driver tries to execute queries on the killed connections without knowing the connection is not existing.
The solution that worked out for me is to set maxIdleTimeMS=45000 in connection string.
This way driver will not use a connection which has been idle for long time.
Here is the connection string that worked out for me
connectionString="Username:Password#hostname.eastus.cloudapp.azure.com/?connectTimeoutMS=30000&socketTimeoutMS=30000&waitQueueTimeoutMS=30000&maxIdleTimeMS=45000"
I have had a similar error with my Azure hosted MongoDb (Cosmos Db). It turned out to be network settings such that I had blocked all access. Changing it to Allow access from "All networks" fixed the issue.
The error is very misleading, I would have expected a connection timeout.
A timeout occured after 30000ms selecting a server using
CompositeServerSelector{ Selectors =
MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector,
LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000
} }. Client view of cluster state is { ClusterId : "1", ConnectionMode
: "ReplicaSet", Type : "ReplicaSet", State : "Disconnected", Servers :
[{ ServerId: "{ ClusterId : 1, EndPoint :
"Unspecified/XXXX.documents.azure.com:10255" }", EndPoint:
"Unspecified/XXXX.documents.azure.com:10255", State: "Disconnected",
Type: "Unknown", HeartbeatException:
"MongoDB.Driver.MongoConnectionException: An exception occurred while
opening a connection to the server. --->
MongoDB.Driver.MongoAuthenticationException: Unable to authenticate
using sasl protocol mechanism SCRAM-SHA-1. --->
MongoDB.Driver.MongoCommandException: Command saslContinue failed: Not
Authenticated.
To troubleshot I tried from MongoDb Compass as well and that didn't work either, showing me it wasn't the code.
I am trying to use mongoDB MMS backup functionality. I am getting the following error when trying to connect in the "Add Host" part of the wizard.
Unable to detect host within check interval.
I have MongoDB 2.6.4 on a my Windows 7 laptop. I've created an admin user with the following privileges:
> db.createUser(
... {
... user: "admin",
... pwd: "xxx"
... roles: [
... "clusterAdmin",
... "readAnyDatabase",
... "dbAdminAnyDatabase",
... "userAdminAnyDatabase"
... ]
... }
... );
I run mongod --auth.
Now I try to connect via MMS using MONGODB-CR Auth mechanism and get the error I described above.
In the log I get many errors like the following:
[2014/10/21 09:13:59] [monitoring.info] [monitoring-agent/components/agent.go:551]

Using Robomongo 0.8.4 client I was able to log-in using the user and pass.
I want to be able for MMS to connect to my local machine and initialize a backup of the databases on my machine.
Thanks in advance.
I had this error while configuring my mongodb-mms. On my Ops Manager server I had configured my TLS connections correctly, but on the mongo server being monitored I had the incorrect TLS certificate. The log /var/log/mongodb-mms-automation/monitoring-agent.log on the agent I was trying to monitor helped me out:
[2020/04/26 02:05:47.363] [discovery.collector-mongo2:27017.error] [components/discovery.go:contexts:580] Discovery commands requiring authentication will be skipped.

See this page to add in your mms user so that the user can authenticate correctly (or fix your certs if it's just a mixup).
