Okey @Aldevinas. We talked about that today. Ill think we might try that. Don´t know if it´s still a problem in juni version. If so we will try do that!
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...
