Why doesn't cerbot work?

Question

linux

Please help, it worked before. Now, when I try to run certbot for nginx, I get this:

Answer 1

Check configs and remove comments in Russian (utf-8). I have decided so. Something is wrong with certbot's parser.

Answer 2

Good afternoon. The same problem began to appear in the letsencrypy.log logs. There are no comments in Russian in configs. I checked the config in /etc/letsencrypy. Help what can be.
My log is /var/log/letsencrypy/letsencrypy.log
