[Bug] LS Docker Container on UnRAID = No Devices Discovered

[door665]

Describe the bug
I've deployed linuxserver docker container on my unRAID server as found in the community apps.
I'm using Cloudflare ZeroTrust tunnel, Pairdrop page opens up fine but it can't find any devices (same network). But if I create a public room it can then see the device.

To Reproduce
Steps to reproduce the behavior:

1. Deploy docker container in unraid
2. open the website

Expected behavior
Expectation is for devices that have opened the pairdrop instance webpage to be discoverable in the same network.

Desktop (please complete the following information):

• OS: unRAID 6.12.10
• Browser: Firefox and Chrome

Bug occurs on official PairDrop instance https://pairdrop.net/
No
Version: v1.10.10

Bug occurs on self-hosted PairDrop instance
Yes

Self-Hosted Setup
Proxy: Cloudflare ZeroTrust tunnel
Deployment: docker

But if I create a public room it can then see the device.

That means, that your devices connect to the devices correctly and only the auto-discovery feature is not configured properly. If you use cloudflare zerotrust tunnels you might need to setup forwarding of client IPs in Cloudflare so that PairDrop receives the real client IPs in the cf-connecting-ip header.
Also, if you're devices connect to your server via IPv6 you might want to checkout IPV6_LOCALIZE env var in the docs.

See documentation how to debug the IPs that PairDrop receives for clients here: https://github.com/schlagmichdoch/PairDrop/blob/master/docs/host-your-own.md#debug-mode
