Certificate renewal: Failed authorization procedure

eigen-value · June 4, 2020, 12:32pm

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: angel.cenel.it

I ran this command: certbot renew --dry-run

It produced this output:
Attempting to renew cert (angel.cenel.it) from /etc/letsencrypt/renewal/angel.cenel.it.conf produced an unexpected error: Failed authorization procedure. angel.cenel.it (http-01): urn:ietf:params:acme:error:una uthorized :: The client lacks sufficient authorization :: Invalid response from http://angel.cenel.it/.well-known/acme-challenge/d4d-kRS6CYAwBoVpq2iYTfKrx5WAnbyAgOs0w6SsmCE [139.162.185.155]: " tml lang=“en”>HTTP Status 404 \u2013 Not Foundbody {font-family:Tahoma", www.angel.cenel.it (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://www.angel.cenel.it/.well-known/acme-challenge/wspEUAELBHu-mvWsWsvcXITYRehPch_LwiQb9BilTkg [139.162.185.155]: “<!doctype html><html lang=“en”><ti tle>HTTP Status 404 \u2013 Not Found<style type=“text/css”>body {font-family:Tahoma”.

Well that is a BIG sign.

Let's have a look at this file:

Also, this may be a key component to this problem:

It is a big sign indeed, but DocumentRoot exists and .conf file is not empty here is the content:

        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this

OK then only thing that looks somewhat out-of-place is:
RewriteEngine on
RewriteRule ^/$ /app [R]

If you can save that entire file as a backup, replace it with this (as a test):

<VirtualHost *:443>
        ServerName angel.cenel.it
        ServerAlias www.angel.cenel.it
        DocumentRoot /opt/tomcat/webapps/ROOT

        JKMount /* ajp13_worker

        Include /etc/letsencrypt/options-ssl-apache.conf

        #RewriteEngine on

OR:

I tried both, then I tried removing all the rwrite rules in the port 80 Vhost as well. Restarted apache and tomcat then tried a dry-run but the output didn’t change…

eigen-value · June 4, 2020, 9:18pm

I solved the problem finally. It was a mod_jk problem.
I removed the JKMount directive and used mod_proxy instead
