Hello! The only way I am able to connect to any of my PCs from my Samsung Galaxy S10e (Android 11) is if I set the default settings to one computer using RU's ID server (normally I use custom ID server). If I try to change anything in the connection properties, even the name, I usually get External Exception C6, 1, or 90 errors.
When I don't get the External Exception errors, I am still unable to connect (except when setting default as above). I run a custom ID server but I usually use direct connect with port forwarding using IP address. I've tried using IP, DNS, using custom ID server Internet-ID, and RU's ID server, using WiFi and cellular connection... all fail to connect.
I still love RU, of course. My computer connections work great! I love that I can create custom ID server and have stand-alone applications.
Thank you!
