Hello,
A 500 error wouldn’t be related to your firewall; as it’s a server error. This means the request has reached your server, but the server isn’t processing it normally for some reason.
It’s impossible to know from this error what the exact problem is, for that you’d need to check your Apache logs. You can do this with:
sudo tail -20 /var/log/apache2/error.log
That should tell you exactly why that request is failing.

Hi @rbjassoc
No, error code 500 means that something went wrong on the server. Read more here: https://www.digitalocean.com/community/tutorials/how-to-troubleshoot-common-http-error-codes#500-internal-server-error
But we have to look at the error log to see more information. Unless the default error log location is changed, then use this command to show the last 30 lines:
tail -30 /var/log/apache2/error.log
