I recently switched from the free hosting to a Pro self-hosted plan, and before the switch, my softphones worked flawlessly.
Desk phones (SBC connected) and the Web Client have no problems making and receiving calls. Both the iOS and Windows apps begin provisioning successfully (scanning the QR code logs me in, and I can see extensions), but the status remains stuck on "Connecting," whereas before it would say "Ready to Call." Incoming calls ring on the devices, but when I try to answer, the app freezes. When I attempt to make an outgoing call, the line remains empty, with no 3CX or SIP provider message.
Nothing shows up in any log viewable from the web interface, but when I exported the support logs, I found a ton of these error messages in the 3cxmanagementconsole.log

I've used a VPN to "locally" access the machine, even trying to place my iPhone on the same VLAN as my local SBC, but no dice.
I'm hosted in AWS, with the automatically populated security group, so I'm fairly sure the firewall isn't an issue. I double-checked to ensure everything matches the port list in the documentation, and the firewall check in 3CX passes with no issues.
I'm about to pull my hair out over this. I've found similar issues on the forums, but searching for short keywords makes it difficult to find relevant posts. Most of the fixes I've come across haven't worked for me so far.
