Currently using MacOS Monterey on a 2019 16" MacBook Pro. I haven’t tried using this app since Catalina, and it was working then. I haven’t been able to get the app to connect to my server over the local ip or remote hostname. All I’m seeing are endless spinning wheels. Both addresses work fine on my Android and Windows apps. I’ve tried deleting the app while using AppCleaner, installing from the latest GitHub release and the app store to no avail.
The issue was that safari was not opening the login page. I had to quit and reopen safari before it would open the login pages. I’m not sure if it’s because it isn’t my default browser, but this behavior is not intuitive at all, there were no messages saying to expect safari to open for authentication.
