Here I encountered an error on my database connection.
I've read some references but still can't find the answer to the cause of this error.

Trying to connect to an external datahub from a SSMS on a server. From desktop computer works.
Port 1433 allowed on server. Has anyone seen this or have a solution? Thank you.
Error:
Test connection failed because of an error in initializing provider. Client unable to establish connection due to prelogin failure
TCP Provider: The specified network name is no longer available.
Client unable to establish connection
Client unable to establish connection because an error was encountered during handshakes before login. Common causes include client attempting to connect to an unsupported version of SQL Server, server too busy to accept new connections or a resource limitation (memory or maximum allowed connections) on the server.
I have an instance of Azure Hybrid Connections running on a server where SQL Server is installed.
I hosted an WebApp on azure, set up the hybrid connection and I'm consistently getting the same SSPI Handshake error
SSPI handshake failed with error code 0x8009030c, state 14 while establishing a connection with integrated security; the connection has been closed. Reason: AcceptSecurityContext failed. The operating system error code indicates the cause of failure. The logon attempt failed [CLIENT: 1x.xx.xx.xxx]
As described here I added the clients ip in the local security policy.
I also tried adding the DisableLoopbackCheck=1 in HKLM\System\CurrentControlSet\Control\LSA, but it didn't help either.
Do I have to fix it on a database level perhaps?
As per https://github.com/Huachao/azure-content/blob/master/articles/app-service-web/web-sites-hybrid-connection-connect-on-premises-sql-server.md
[AZURE.NOTE] To ensure that your application uses the database that you created in SQL Server Express, and not the one in Visual Studio's default LocalDB, it is important that you complete this step before running your project.
Edit the connectionStrings section to point to the SQL Server database on your local machine, following the syntax in the following example:
I added user credentials to my connection string in appsettings.json and it now works.
After restarting my PostgreSQL on Azure Database Instance, I can no longer connect via any client and I receive: psql: SSL SYSCALL error: EOF detected with psql.
I used the Restart button on the Azure Database for PostgreSQL server overview page.
Most likely server was in the process of rebooting. Check in the server logs server start time. Probably it will be after you issues your connection request. If you have heavy workload running then recovery is expected to take longer.
When publishing MVC app on Azure, the connection string is picked automatically but I fail to understand how the deployed app connects to the database using this connection.
There's server error: 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.
How do I resolve this on Azure.
In my rake task, I'm connecting to postgresql via a pgbouncer setup. For some queries I receive this error:
ActiveRecord::StatementInvalid: PG::ConnectionBad: PQconsumeInput() could not receive data from server: Connection timed out
In my pgbouncer log, I see this entry:
closing because: client unexpected eof (age=3110)
I have disabled prepared statements in my config/database.yml file and enabled transaction pool_mode in my pgbouncer config file.
When I directly connect to postgres, I don't get this error.
Also in my rake task, I am creating multiple threads. I tried running ActiveRecord::Base.connection.reconnect! inside my threads as suggested here. That didn't help either.
I am using rails version 4.2.5 which has this fix. I'm still getting this error "could not receive data from server: Connection timed out".
This was caused due to network issues in clients. Not able to reproduce since we migrated both server and client to Google Cloud Platform. Earlier our server was in DigitalOcean while our clients were in GCP.
