Not able to connect MongoDB Compass
Hi, krl! I was getting the exact same error from MongoDB Compass Community 1.11.1 while trying to connect through an SSH tunnel, with a ppk file protected by a passphrase.
Are you putting your remote server IP or domain name in the first field (hostname)? That was my mistake.
What solved it for me was setting the Hostname field (the first one on top) to localhost instead of remote server IP or domain name. Put your domain/IP only on the field SSH Hostname.
I hope it helps.
