Upgrade from SLES 11 SP4 timeout registration service

I’m trying to upgrade a SLES 11 SP4 for SAP Apps to SLES 15 for SAP Apps (offline), it seems to have networking and Internet access yet during the registration check process it just hangs and times out. The logs don’t give me much to go on. Any way to troubleshoot this?
