VitalPBX Issue-Hoes offline for no reason intermittantly

|Debian GNU/Linux 11 (bullseye)|
|Kernel|5.10.0-26-cloud-amd64|
|Asterisk|18.17.1|
|VitalPBX|4.0.3-5|
|PHP Version|8.1.11|

Having intermittent issue with 2 separate VitalPBX instances.
For no reason, server is not available for SIP or SSH. Have to force stop the instance and then restart. Nothing out of the ordinary in /var/log or any other logs from what I can see.
