I've got PSQL Server (Tried 13 and 14)
A very basic setting. One small DB.
One user with password.
in pg_hba I have configured access from network (md5) to those databases.
When I connect from Server host everything is ok, I can do everything I want.
When I connect from remote machines (any) I successfully connected.
I can see databases, connection settings. Everything looks fine.
But when I just do "\dt" or many different things client hangs.
Nothing is doing, and it's not timing out.
I've stopped Server and this client didn't get this.
I'm using this on Ubuntu 20.04 most actual software available today.
Does anyone have idea what is going on?
On server side logs I can only see that client is lost and that is all.
Best Answer
There was problem with MTU between client and server.
