I use nginx, and when I try to add a certificate this error comes out. Does anyone know what the problem is?

Yes, the issue is that Certbot was installed using global pip on this server. Installing Python packages globally like this is very brittle and we strongly recommend that you don't do it.

Alternative installation methods are:

More precisely, the versions of these Python modules need to be in sync:

  • acme
  • certbot
  • certbot-nginx

That said, I also think you may need to deal with the DNS issue:
1.1.1.1 can't find bitwarden.didziojipilis.eu: Non-existent domain

Maybe not to obtain the cert - you could use DNS-01 authentication for that.
But, when you go to use the cert, without a DNS entry it may be a bit difficult.
