The only thing added to this was the proxy reverse to eliminate :8181 from the URL. It worked fine before and after this httpd.conf addition.
Maybe if I disable the proxy reverse and enable LE in GitLab, maybe it will renew when the limit expires?
Maybe, but might be best to renew manually to avoid any issues with flooding the LE system and locking yourself out indefinitely...if you use certbot and the renew option, it will only request a renewal if it is needed, otherwise it will inform you that it isn't needed and won't submit an actual request.
On my server, I did it like that the first few times, and then put the command in a script and created a cron job for it.
The script is simple:
#!/bin/bash
sudo certbot renew
And the crontab file for ROOT contains:
@monthly /home/riveraa/bin/renew
Which as you can guess, runs the "renew" script once a month.
AIR.
