Failure to connect using Oculus online subsystem

Using the oculus online subsystem I have not been able to join another users session (matchmaking or room). I've integrated the Unreal OVR SDK sample, added my oculus app ID, changed the matchmaking key to my own which is user and system created, and am running two separate packaged instanced on separate machines that are using separate internet connections so that unreal doesn't revert to it's own subsystem that I've seen can happen automatically over LAN. I can search for sessions correctly and see what oculus user is hosting but always fail to join.

I've included my log files that show a connection being attempted but I can't figure out the exact issue that's stopping a connection from being accepted. The pertinent line seems to be:

[2021.05.22-00.56.06:086][226]LogNet: UChannel::Close: Sending CloseBunch. ChIndex == 0. Name: [UChannel] ChIndex: 0, Closing: 0 [UNetConnection] RemoteAddr: 4097954510325963.oculus, Name: OculusNetConnection_2147482471, Driver: PendingNetDriver OculusNetDriver_2147482472, IsServer: NO, PC: NULL, Owner: NULL, UniqueId: INVALID

Also after I call the 'join session' node in BP I get a successful response but in the log I get

[2021.05.22-00.56.02:491][903]LogOnline: Warning: OSS: The World Does Not Exist.

I am including the network map in the list of maps to include in a packaged build.

This is how I'm calling the create session/ join session:

Here is a link the same question on Unreal answers where I've uploaded the full log file of the client trying to connect (couldn't see how to upload it here)

Thank you for any help, I've been working on this for 3 days *crying emoji*
