[BUG] Certbot fails

[urshofer]

Certbot started to fail suddenly after years of working without problems. If i disable badbot blocker, certbot works as expected.

Domain: xxxxx
Type: unauthorized
Detail: xx.xx.xx.xx: Invalid response from https://xxxxx/.well-known/acme-challenge/xxxx

I guess the IP of the certbot servers are somehow blocked...

Probably linked to this?

I've seen this also.

My solution was to comment out this line in conf.d/botblocker-nginx-settings.conf:
server_names_hash_bucket_size 256;

@numediawebsites do we need to uncomment this line after certbot renewal?
