Rant: What's the problem with EL7/8/9?

What you describe, could well be an issue. I could not reproduce my problem. It was an Ajax error during the initial firewall setup.

Firewall Ajax error during initial setup on new freePBX 16 distro install

On a new freePBX 16 distro install the firewall wizard crashes with an Ajax related error, once the standard settings (two or three mouse clicks) are confirmed. It works when you reload the web-gui and do it again…

I installed a new system at another location, but did not see the error…
