I’m having trouble upgrading a SLES 11 SP4 to SLES 15 for SAP apps. It’s
of course an offline upgrade.[/color]

Before the upgrade happens did you have the system configured to get
updates from SUSE? Did that work at the time?

It boots fine, pass the screens until it wants to connect to the
registration services but then times out, logs don’t give me much clues
beyond that. Is there a way to troubleshoot this?[/color]

Have you tried switching over to a TTY to test networking, or maybe try an
HTTPS connection directly yourself?

Do you have other systems on the network which, at the same time, can
reach SUSE’s update service (other SLES boxes perhaps)?

I seem to have network, I can ping/resolve suse.com fine. Any tips

Being able to resolve is good, and pinging is a useful start, but ping
uses ICMP, which is a sibling of IP, so it’s not really the same thing.
Having those good steps done, let’s also try a better step of verifying
TCP/IP with netcat, or even going up to the application layer (layer seven
(7)) with curl:

netcat -zv updates.suse.com 443  #I'm guessing at the DNS name there

curl -v https://updates.suse.com:443/  #guessing here too

Good luck.
