279 error on specific experience when joining with a specific DatacenterId

I have an issue where the game I’m working on will randomly encounter 279 errors upon joining, either from a teleport or simply pressing the play button. Upon inspection of the client logs, the only commonality between failed joins is that they all have the same DatacenterId and every successful join has some other DatacenterId. This has happened at least a dozen times. It seems to only happen with my experience (I can’t confirm this though. I just have no examples of joining another game with this ID on my PC right now). I know the server isn’t hanging on start either because I have a debug service that writes to a MemoryStore to report server stats, and the failing servers show up until they close due to ServerEmpty. I have attached the DatacenterId, the place/universe ID, and a client log in the private section.

Same issue here for me, and the same pattern: every 279 is on one DatacenterId, every successful join is on others.

From my client logs on Oct 4: all 3 of my 279s were on DatacenterId 26065, and all 21 successful joins were on other DatacenterIds.

All three failures are teleports from my lobby to a reserved server (TeleportAsync with ShouldReserveServer). TeleportAsync succeeds, TeleportInitFailed never fires, and the client gets “Connection attempt timed out after 10000 ms”, then “Failed to connect to server … no response” (279). Rejoining and teleporting again works when the new server lands elsewhere.
