On my Side it seems that the Problem with the wrong Port is NOT solved in 3.4.7. On my Side the Ports from each Connection changed autmatical back to 21 as described in this case: https://community.sftpapp.com/d/26-wrong-port-when-adding-an-ssh-connection-since-3-4-6
Same here again. Each day i must change some ports back to 22 I wonder is was working after Upgrade to 3.4.7 for a few days.
I keep experiencing same issues
