Cloudflared Tunnel frequently unavailable (502: bad gateway)

My cloudflare tunnel (1eca4591-45e1-4b70-9ad1-90ae40d8db30)

Is experiencing very frequent outages that result in a 502: bad gateway.

Refreshing the page on my domains multiple times usually results in the tunnel to work again after some time.

I set up a fresh tunnel using version 2024.4.0, but the issue persists.
From my local network I can access my pages the whole time, even when cloudflared responds with a 502. A connection to the internet is also available and working the whole time.

I think I found the culprit.

One of my VMs was using the same static IP as the VM I was trying to access. This way some connections worked, while sometimes they failed.
