I emailed Yum and got this:
After input the IP address, click OK and SKYBOX will try to coonect The server address you input. If you are not able to connect, what error message do you see please?
If you still encounter the issue, please
send the log file Android/Data/xyz.skybox.player/Files/PersistentData/OutLogs.txt and SKYBOX/SKYBOX_debug_log.txt to me so we could study what's going wrong.
After work today I'll try to set back up and send the logs. I have an UnRaid server and running this on the Oculus Quest 2
