JotServer restarts

Hello dear Unitarians. Several times a year, the Messenger app fails. Connections do not connect. Usually a server restart fixes this issue. Yesterday, it did not. Leading me to ask: Does the Jotserver itself need to be restarted in addition to the server restart?

I checked the certificate. It looked OK. Any ideas why jotserver fails about every 3 months? We're hosted by TMD, by the way.

In the php error log, I see but cannot interpret: .... modules/boonex/messenger/classes/BxMessengerTemplate.php on line 1591[10-Dec-2024 15:02:20 UTC] PHP Deprecated: Implicit conversion from float 1.1333333333333333 to int loses precision in 

This error appears more like a visual template issue than one relating to connectability.
