So I've recently gotten into building out a home lab, and I want to
use Teleport for my access management.

The problem I have been experiencing is that I can't seem to get
multiple devices to connect to the Teleport at the same time. I first
discovered the problem while attempting to enroll a Proxmox VM on my
server in teleport; I had a connection to the Web UI open on my PC to
follow the enrollment steps, but my virtual machine would fail to pull
the deployment script from teleport. I then found out that I couldn't
connect to the Teleport Web UI on multiple devices on my home network;
already signed into Web UI on my PC, I would fail to connect to the
Web UI on my phone when it's on the home network, but if I disable Wi-
Fi and used cellular it would connect with no issues.

I don't have any fancy subnetting or VLANs (yet), and my PC and the
server are connected via Ethernet. Here are some of the things I have
tried/checked (will update as suggestions come through):

* turning everything off and turning it back on again
* reinstalling Proxmox
* reinstalling Teleport
* checking my virtual and physical machines can otherwise connect to
the Internet and talk to each other
* checking my virtual and physical machines can otherwise connect to
Teleport Web UI if they are the on device trying to connect
* ensured Proxmox Firewall rules are set correctly (also tried
allowing all traffic, with no luck)
* ensured port forwarding rules are set correctly
* checking teleport logs for errors
* asking Teleport Slack community for help

Any and all additional troubleshooting tips + suggestions are welcome.
This problem has been plaguing me for months and I'm about at my wits
end.
