I got several messages regarding renewal, and today managed to get around to it. To my surprise after issuing
sudo certbot --apache
Error while running apachectl configtest.
AH00526: Syntax error on line 1 of /etc/httpd/conf/le_http_01_challenge_pre.conf:
Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration
While a file by the name of /etc/httpd/conf/le_http_01_challenge_pre.conf: doesn’t exist on the server in question, running
sudo apachectl configtest
To make a long story short, the solution was, to uncomment
LoadModule rewrite_module modules/mod_rewrite.so
I think the error message could be more to the point…
What version of certbot are you using? Perhaps this issue has been resolved already in the most recent version.
Also, the file le_http_01_challenge_pre.conf is only used and installed for/during the http-01 challenge, so the fact you can’t find it after certbot is done running, is perfectly understandable and normal. However, certbot should enable mod_rewrite when it’s doing the challenge.
