question

"I use that in my requestMutltiplayerServerRequest to login to the active server."

By this I mean I use the exisiting sessionID from the active server in my requestMutltiplayerServerRequest as opposed to generating a new one. It is my understanding that if you provide a sessionID from an existing active server, then the the response contains the information from that server.

This works for me. When I test, I have a server on standby, no sessionID. Client 1 requests a server and a new one is spun up using a generated Guid. The server is now active, and client 1 is logged in.

Client 2 then requests server and since there is an active server, it is sent the response containing the active server's information. Client 2 then logs in.

I have an Azure function that gets a list of servers and returns the sessionID of the active server if there is one. This sessionID is then used in the request. The response contains the correct data for the active server (I have tested all of this)

All this works fine. However, after a short period of time (less than 20 min), I can no longer have new clients log in. That is when I get the above mentioned errors.

Thanks for your time

This post explains what I'm doing regarding the existing sessionID.

Edit: so I tried entering the ip and port directly once I start getting the error, and it connects fine. I also tried using the GetMultiplayerServerDetails if the server is active, and RequestMultiplayerServer if not.

Now, the first client activates the standby server and connects, but immediately any other client that tries to connect gets an error from GetMultiplayerServerdetails, which is

"Invalid JSON in request 1-6320c0c1-51cb97d27ebce82d6196c47f ValidationError: Cannot convert null value to Utility.AzureRegion. Path 'Region', line 1, position 47."

The code for calling it is

GetMultiplayerServerDetailsRequest mpRequest = new GetMultiplayerServerDetailsRequest()
             {
                 AuthenticationContext = titleContext,
                 SessionId = sessionID
             };

PlayFabResult<GetMultiplayerServerDetailsResponse> serverDetailsResponse = await PlayFabMultiplayerAPI.GetMultiplayerServerDetailsAsync(mpRequest);
