Suddenly can't access frontend

[CPT]

Hello,
I use to be able to access the zabbix frontend via the url http://zabbix.domain/zabbix. Earlier I was creating a template, I clicked the "Add" button, and now the front end is completely inaccessbile. When I try to go to it, it redirects to my companies website at the root domain. The application is still running and operating as expected. I can see it on the Ubuntu server when using "systemctl status zabbix-server", and I have gotten alerts for triggers in the templates that have been assigned. I just cannot reach the front end anymore. Anyone know what I might have done to cause this?

Please post your Zabbix server version, web service package (nginx or apache), and operating system version.

Hello,
I'm using Zabbix 6.4.2 running on Ubutnu 20.04 with Apahce 2.4.41. I'm just using the out of the box setup for Zabbix without any modifications in terms of webserver.
A couple of things to note, when I run a curl command against the url I'm getting a 301 error. I found that the website had failed to reload due to the mod_rewrite package not restarting for some reason. I manually reinstalled it, ran the apache commands to start the webservice, and it came back up, at least from the CLI. Now though when I go to the website the webpage is loading, but it's not populating anything. So I can see the landing page, but there is nothing there. No data, and none of the drop down menus on the left hand side show anything when I hover over them and click on them. Also, I'm not getting a login page when I go to the site. It's just taking me straight to the monitoring page but there's nothing there, and I can't sign out.

So I've gotten the webpage back up, and it's mostly working, but I'm still encountering one issue. I can see almost all of the pages from the Lists on the left side of the webpage, except the Templates webpage. When I click on the link for that, it redirects to the my companies website at the root domain with /template.php as the end of the URL. No other link is doing this so far.

My information may be a little different than yours. We're on 6.0.19. There are 3 directories we care about (I'm assuming this is running on Linux...)

/etc/zabbix/web/
This is where you should be defining access to the web front end (allowed IPs, PHP settings, etc). In a default setup, all you likely care about is $ZBX_SERVER_NAME and the $DB section (+/- the Postgres specific section). That file would be /etc/zabbix/web/zabbix.conf.php. Make sure those are set up correctly.

Check these files and make sure they're not redirecting anywhere unexpected:
/etc/httpd/conf/httpd.conf
(May not exist) /etc/httpd/conf.d/ssl.conf
/etc/httpd/conf.d/zabbix.conf
cd /usr/share/zabbix/ && egrep -i "redirect" *.php
