Stuck on "allowing new devices to join:"

[shadowa4]

Good afternoon,

I've searched this and other forums for the answer, but I just cannot get my Z2M installation to launch successfully. I followed this guide to install Z2M on my RPi4, which is also running homebridge and Unifi. I am continuously stuck on the "Allowing new devices to join" line, after which the only way to progress is to ^c, after which you see the errors below. I am aware that Unifi has a conflicting port (8080), for which I've also tried changing the frontend port to 8099, 9090, anything else. Still, fails to start.

I've tried deleting related Z2M directories and starting over, but nothing changes. I will say, this whole installation broke once I realized that port 8080 would be an issue and started adding an alternative port. While using port 8080 it would actually start at first, but would warn me that the port was conflicting. Now if I use port 8080 or any other, I get the issues below. My yaml config is below as well, but looks pretty standard to me. Any ideas?
