I have just installed a fresh copy of 3CX Phone System. PBX is working as expected all softphones and regular phones provision and can make and receive calls. Unfortunately 3CX MyPhone doesn't appear to be working correctly. I can connect to the mydomain:5000/myphone webpage, and the logon dialogue appears. I enter an extension and a password, and then an error appears (umm... that's me). I have no clue where to begin troubleshooting this error, as I can't find any settings for 3CX MyPhone in the System Management console, all other features are working without a hitch, and the firewall checker passed all tests. Any help is greatly appreciated. Thanks!
