How to "Reset" Domain Controller
#2

Is port 80 opened for access from internet?

#3

Its without Letsencrypt. I only use selfsigned Root Certificate of the server. Do i need P80 for selfsigned?

#4

The less information, the less help is possible.

Which certificate do you want to renew - the root certificate or the server certificate?
The server certificate is self-signed, too?
What is the Univention server version?

#5

In the Past all my univention servers got SSL Certificates from my Reverse Proxy via acme and rsync to a location and entry in ucr variables.

Yesterday i removed the apache2 entries with my certificate of my reverse proxy rollout to all servers, cause the Univention Server no need a certificate now.
So i renewed the Root certificate and only want use selfsigned certificate for the Servers and used the documentation of: Renewing the SSL certificates

Version: 5.0-1 errata310.
