Sudden MID Server Connectivity Failure

Our MID server suddenly fails to connect to the instance every now and then. We are looking at understanding what is causing this issue and try to optimise it from our end. I am unable to understand what might have gone wrong as the below log shows a heartbeat and a sudden connection failure.

Can anyone please guide me how to debug or what next steps can be taken to avoid this issue frequently.

Thanks!
