Hi, I'm using Debian Stretch and I'm trying to connect to PostgreSQL server (Debian 9) with PgAdmin (Debian 9) through SSH tunnel. PgAdmin has built-in SSH support but when I try to connect to remote PostgreSQL server I get this error in PgAdmin: Error: SSH error: Error when starting up SSH session with error code -8 [Unable to exchange encryption keys] I use key pair for OpenSSH authentication. Any ideas what is wrong? Kind regards Georgi
