Your Subscription with FQDN sxtel.my3cx.de appears to be offline for an extended period of time.

Check your network config. Firewallcheck ok?

 

[Saxon]

are these two problems related?

 

[Saxon]

by ip everything works

 

[bitn2]

We would like to inform you that if your 3CX System with the above subscription remains offline for another 10 days, the associated FQDN will be released from this subscription.

The server has been running for over a year, I haven't changed any settings. Dashboard - FQDN glows green

You need to upgrade to V18, as 3cx have changed system settings i.e. activation servers.

The main issue you have is server 2016 is not supported any more. - https://www.3cx.com/docs/manual/phone-system-installation-windows/
