The above link is not public.
The issue does not seem Raspberry specific. I suggest to find a proper topic related to MQTT communications for continue.

Mono framework can have memory leaks. .NET 8 is much better.

> When I upgrade to version 6, do I need new license keys?

If a communication line is working as TCP server, make sure that incoming connections are enabled in the firewall settings.

Hello,
Usually 4G modems are not available by IP from outside. Telecom operators sell white IP addresses. Another solution is using VPN.

Looks like an out of memory error. How long does it work after rebooting the Raspberry?
In general, I recommend to upgrade to Rapid SCADA 6 which uses modern .NET framework.

Hello,

To store last communication time, you need to create a new channel, and develop a formula that stores the time in that channel.

Keeping last good value can be done by the formula.

Hello,

In TCP communication, a connection brakes silently sometimes. If a client cannot poll a server, it must reconnect if there is no reply or connection is idle for a period.
