@scottalanmiller my support forum has pretty low traffic, so it’s not really an issue 😊
Actually the version of postgresql I had to install on my server doesn’t seem to be compatible with my install of Plesk either.
But it works well, and I don’t have to mess around learning how to support mongodb.
Try connecting manually. Use the mongo client and see what that does using the creds that you are attempting to use.
