Timeout after a few hours of usage

[lupus78]

I'm running the app with this command on a raspberry pi 4:

./GoSungrow mqtt sync > output.log 2>&1 &

It works fine, but after a few hours the requests start to timeout an stay like that. Here is a snippet of the output.log:

After the first timeout it never resumes. But! If I stop the process and start it again, the connection is working again.

Am I doing something wrong, or Sungrow is trying to make our lives harder? :)
