SSH Tunnel Broken on version 6.14

I’ve been using PGAdmin V5.0 to SSH Tunnel to an AWS RDS PostgreSQL DB through an AWS EC2 VM for quite a while now with no problems.

The tunnel uses a pem key with a password.

Luckily I didn’t uninstall this version as I can still get connected, however yesterday I installed V6.14 but keep getting a ‘cannot establish SSH gateway’ error message as follows!!
