Hi Bror-Erik, I didn't create a bug report because I know one already exists. I'm not sure who reported it though. If you can't find it, I can create one.
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...
