It would be good to have a test button to check the connection, this reduces unnecessary back and forth decphering log messages on both ayon-server and kitsu-server end.
This can be checked from the kitsu tab is studio settings.
the list will appear empty if the connection fails.
Also, keep in mind, for your kitsu server url, please use the url that you’ll use when you want to log into your kitsu from other devices on your network.
