Describe the bug

When I try to get a new certificate I get an Internal Error I thought there was something wrong with my settings so I tried with a lot of different variations, restarting docker, restarting the system, etc, but got the error every time. I went into the logs & saw this error An unexpected error occurred: AttributeError: module 'certbot.interfaces' has no attribute 'IAuthenticator'

I tried altering a bunch of different things but always had the same error. I edited an existing Host that was working fine & requested a new certificate & got the same error. I created a new Docker that was essentially the same as the old one in the docker compose but went to a different directory for the mounts. When trying to run it I ran into an error because I have mapped - /g/docker/nginx/nginx.conf:/etc/nginx/nginx.conf because there’s no other way to have the nginx.config persist without having the whole /etc/nginx directory which causes problems. I copied over the nginx.conf from the previous installation & started the app anew, creating the user account & then attempting to create a host. When I did I got the same Internal Error again. I removed the mapping for the nginx.conf, started the container copied it’s nginx.conf from the CLI to a directory that was mapped, & replaced the old one with the new one, then deleted everything except for that & started fresh again. I got to the Adding a Host point & again ran into an Internal Error which was again in the logs with a An unexpected error occurred: AttributeError: module 'certbot.interfaces' has no attribute 'IAuthenticator' A clean install has the same problem, so I’m now certain the error in not mine but with the app itself. Also in the logs, at least the last few rounds I tried, is this error [11/25/2022] [4:28:32 AM] [Express ] › ⚠ warning Command failed: certbot certonly --config "/etc/letsencrypt.ini" --cert-name "npm-1" --agree-tos --email "##REDACTED##" --domains "##REDACTED##" --authenticator dns-duckdns --dns-duckdns-credentials "/etc/letsencrypt/credentials/credentials-1" I also have confirmed the domains are correct & have tried different domains that are currently active in my old-version so long as I do not attempt to get an updated certificate for them.
