I'm struggling to understand SLES aarch64 options for the RPi. Hopefully someone can clear this up.

My subscription for SLES 12 SP2 expired.
How do i get extend/buy a new subscription?
AFAICT not through scc.suse.com and not here https://www.suse.com/shop/server/

I have developers subscriptions for SLES for ARM.
But I can't download the SLES 12 SP3 ARM iso nor the SLES 15 ARM or the SLES 15 ARM/Pi iso (both say "We're sorry, we are unable to complete the download at this time.")
Is the download server broken (for several days) or is there some issue with my SUSE account?

Thanks
