I have six fusionpbx instances that have been running for months, one of them started giving me this problem:
I no longer see any extensions connected to the server.
All domains contained in this server no longer have extension registrations.

I tried saving a log from fs_cli:

May be useful to understand why it does so? Registration requests seem to come. A freeswitch restart fixes the problem, at least for several hours then the problem comes back.

This server has been running perfectly for almost a year, i never updated anything, it has a lot of free space still on its memory.

Today happen again, server not register gateways (tryng) and not accepting extension connection until freeswitch restart, or system reboot.

I have this extact problem:

Failing to register to SIP Trunks (Gateway) after some time

Hi all, This is kind of new. I have FusionPBX installed on a Debian 11 VM in the Cloud, IP Address (public) assigned directly to the ethernet adapter. Since last night it started behaving a little bit weird, because all Gateways will remain in a TRYING state, not connecting. I've didn't...
www.pbxforums.com www.pbxforums.com

My gateways cannot register with error 980:

freeswitch@CentralinoC9N> sofia status

I have deactivated iptables but the problem persist.
I can ping the gateway server without problem:
