TS QNAP 453A recurring problems

Thank you for that. I tried to create account and I got a sql error!
The story is,it all hard wired and have two qnaps, a older TS412 and a
T453A which is giving me trouble.
Could you tell me how to monitor remotely?
The only thing I have on here now is Antivirus, container station
App Center, control panel and resource monitor.
