Have tried twice now, the compressed backup is 1.3 GB and takes a few hours to upload. Each time before the upload is completed about 90% done, the page refresh to the login screen and all progress lost
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...
