Okay I think I found my problem.
I have apache2 and nginx installed.
But I used apache2 as a web server.
When I performed the update, the apache2 server was deactivated and nginx was activated.
I would like to keep nginx because it is much faster than the apache2 web server.
But now all my web services are running in apache2 mode.
How do I set them up so that they run with nginx.
Unfortunately, I am not as familiar with nginx as I am with apache2.
I would be happy if someone could help me.
Greetings and thanks.
And sorry for my bad English, I'm better speak German.
