"Exception on fd" means the connection with the client has disappeared so we will automatically log off the client. Let me dig a bit on how MS Edge WebView can be the cause of the crash and if it is the culprit, take it up.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
