Good day,

I am having a problem with my connection ro 3CX on both APP and Web. It just disconnected a few minutes ago. Interenet connection is fine and stable.Screenshot 2025-11-18 110942.png
 
Issue on the PBX end then, have you checked all services are running or tried rebooting it? Is this self hosted?

If you can, check if the machine is running ok via console access , if yes it could be firewall issue.

Otherwise it will most likely need to be restarted.
 
HI,
This is self hosted.
The machines are not running ok via console as well. Same reconnecting error even after restarting the machines.
 
You're going to need to start your troubleshooting from where your PBX is living.

What OS are you running?

Does the machine have a static IP?

Can I access 3CX via IP locally?

Can I access 3CX via IP from the LAN? No -> Check Firewall

If the OS is booting up OK and the PBX is not starting, let us know if any type of error is seen.

If the machine is not booting at all then that is probably beyond what the forum can help with, but of course you are free to tell us the symptoms you see, just in case somebody has some idea of steps to take.
 
What OS are you running? + Windows 11

Does the machine have a static IP? YES

Can I access 3CX via IP locally? Not right now as it says it is disconnected

Can I access 3CX via IP from the LAN? No -> Check Firewall NO
