System.Net.Sockets.SocketException (111): Connection refused

See original GitHub issue

The issue

I’m trying to run my migration scripts using dotnet ef database update... but keep getting System.Net.Sockets.SocketException (111) errors. Before you jump to conclusions, I am able to successfully connect to the remote database using psql psql -h <host> -p <port> -U <username> -W <password> <database>.

“Connection refused” means that a socket connection could not be established - Npgsql doesn’t do anything special here, just uses the standard networking APIs. In other words, this is almost surely some sort of environmental issue that’s unrelated to Npgsql - firewall, bad docker config, etc. As a first step it’s always good to try to connect with psql (or any other PostgreSQL client).

Am going to close this for now, because I don’t have any clear information about a problem in Npgsql.

I’m having the same issue. I also created separate network and tried to access the machines using their hostnames defined in docker-compose.yml. No luck. Getting exact same issue. System.Net.Sockets.SocketException (111): Connection refused
