Failed to start Zabbix Server - Can't open PID file

[ITAdminBozeman]

I'm in the process of setting up the latest Zabbix 6.0 on Ubuntu 20.04. I have it installed and updated, MySQL, Apache2, PHP configured, and the basic steps of creating SQL user objects and system users taken care of. We are able to get the server/frontend to load, but it crashes after about 10 seconds with the following error (notes from the Ubuntu log). It looks like a permission issue. Please let me know your thoughts and suggestions. I appreciate any assistance/feedback you can render.

This looks like the system logs, with basic systemd messages. The "Can't open pid file" is annoying, but I don't think it's what's causing the issue.

What's in the /var/log/zabbix/zabbix_server.log ? There should be some obvious start-up messages, including version and what features were selected when the software was compiled, but after those messages there should be a clue about what the problem is.
