Mdns, network, or other issue in BlueOS

Hello community,

There is one problem I have that is strangely appeared out of nowhere, because it just worked yesterday but not working this morning.

I can see this many error messages in the BlueOS (192.168.2.2) of the ROV (connected via tether)
Also I noticed that the name of the vehicle is no longer there,

There is should by default BlueROV or anything you put once you change it, the problem is whenever I try to change the name it returning the Error 502 Code

What might be reason and how I can fix this?
