I failed to create certificate.
I tried to check access using command below (just to check if there is an issue in the web server for this specific folder) and it works
curl -I http://egerp.com/.well-known/acme-challenge/3vGIG540TjxdzS4O_eCm0qi1VaZaDfvQQ9Ib0ZAyaO8
HTTP/1.1 200 OK
Date: Wed, 30 Sep 2020 16:51:46 GMT
Content-Type: text/html; charset=utf-8
So it seems not to be an access problem.
My domain is: egerp.com
I ran this command: sudo certbot --nginx
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator nginx, Installer nginx
