Subscription Key not accepted

[taich]

I have a valid subscription, but my server tells me it is too old. When I issue a check I get Connection error 596. Same if I remove and re upload the subscription key.
Can anyone tell me how to overcome this?

Thanks
Thomas

Seems your host cannot connect to shop.maurer-it.com on port 443.

=> check your network.

There is no firewall on my proxmox server. This is what nmap says:

root@pve01:~# nmap -Pn 79.133.36.249
Starting Nmap 7.70 ( https://nmap.org ) at 2020-12-27 10:46 CET
Nmap scan report for shop.maurer-it.com (79.133.36.249)
Host is up.
All 1000 scanned ports on shop.maurer-it.com (79.133.36.249) are filtered

Is it possible that my IP is blocked?
