[SOLVED] Subscription key ckeck fails: "Connection error - Timeout."

my subscription key ckeck fails with "Connection error - Timeout.". In the beginning this worked but not since 2023-08-10. The subscription is valid until 2024-07-30.

Where can I check for a more detailed error log?

Can the host ping our shop, which is used to check validity?
ping shop.proxmox.com

As the issue doesn't seem to be that the subscription is void or the like, but rather a technical error in the network, somewhere between your host and our shop.

It would be good to check, if there was a possible change to firewall or another network component at the time this started to fail.
For further help w.r.t. subscriptions please use the Proxmox Customer portal over at https://my.proxmox.com/en - for subscription activation/validity issue you can use this even if your subscription level wouldn't cover enterprise support tickets.

ping does work but first via IPv6. Might that be a problem?
If we don't find a quick solution I will use a support ticket.
Ok, I found it: it's the change to Proxmox VE itself. I updated from 7 to 8 and with that the (automatic) behavior regarding IPv6 must have changed. A NIC which did not have an IPv6 address before did so now. And as the firewall did not allow such traffic, the verification of the subscription failed with a timeout.

I found it with
$ pvesubscription get
