Thanks for the offer. I did a bit more troubleshooting and discovered this likely was NAT in the end. What I discovered is if I move the valheim docker off my custom docker network to use host networking (or custom docker that shares the host IP range) that PlayFab was able to stay connected.

No geo blocking in place. Port mapping at my router is 1:1 mapping with open ports on the container as well (confirmed via external portscan of public IP). The oddest thing here is that removing -crossplay works entirely fine for steam users outside my network and for users inside my network. I even deleted the entire container last night and re-created it, same issue is happening. Switched game port to new port (2457) and same issue.

Interestingly, I am having a similar problem to @DIgitalOSH. with -crossplay param removed steam users outside my network can access the server no issue (both IP and hostname resolution work). However when I enable -crossplay I see initial connection, then constant reconnects. .... 03/20/2023 17:09:11: PlayFab logged in as "PlayFab_BroHeim_2456_REDACTED" 03/20/2023 17:09:11: PlayFab local entity ID is REDACTED 03/20/2023 17:09:11: New session server "BroHeim" that has join code , now 0 player(s) 03/20/2023 17:09:11: Register PlayFab server "BroHeim" with IP REDACTED:2456 03/20/2023 17:09:11: Server 'BroHeim' begin PlayFab create and join network for server 03/20/2023 17:09:12: Zonesystem Start 6 03/20/2023 17:09:12: Added 3 locations, 0 vegetations, 0 environments, 0 biome env-setups, 0 clutter from locations_cp1 03/20/2023 17:09:12: Added 1 locations, 0 vegetations, 1 environments, 0 biome env-setups, 0 clutter from locations_mountaincaves 03/20/2023 17:09:12: Added 27 locations, 25 vegetations, 5 environments, 1 biome env-setups, 3 clutter from locations_mistlands 03/20/2023 17:09:13: DungeonDB Start 6 03/20/2023 17:09:13: ZRpc timeout set to 30s 03/20/2023 17:09:13: Load world: BroHeim (BroHeim) 03/20/2023 17:09:13: Loading 234764 zdos , my id 2191084301 data version:29 03/20/2023 17:09:14: Loaded 100000 dead zdos 03/20/2023 17:09:14: Removed 0 OLD generated ZDOS 03/20/2023 17:09:14: Loaded 9971 locations 03/20/2023 17:09:14: Unloading unused assets Unloading 10 Unused Serialized files (Serialized files now loaded: 0) The shader Hidden/Dof/DepthOfFieldHdr (UnityEngine.Shader) on effect Main Camera (UnityStandardAssets.ImageEffects.DepthOfField) is not supported on this platform!

WebAuthn in general would be a great addition here (adopting FIDO standard for passkeys, link for those who want to learn more: https://fidoalliance.org/passkeys/ ) Google, Apple, and Microsoft support the standard today. This would be great to see integrated as a sign-in option to UnRAID, even if it can only support single-device passkeys due to likely lack of BLE availability on most servers that is required for CTAP in cross device authentication scenarios (e.g. browser to mobile).
