Question Is Relay supposed to not work if no connection is created?

Hey everyone,
Is Relay supposed to not work with no connection?
If I just allocate the Relay and get the JoinCode

Code (CSharp):

1.             Allocation allocation = await RelayService.Instance.CreateAllocationAsync(3);
2.             string joinCode = await RelayService.Instance.GetJoinCodeAsync(allocation.AllocationId);

Then on the client if I try to join with the JoinCode

Code (CSharp):

1.             JoinAllocation joinAllocation = await RelayService.Instance.JoinAllocationAsync(joinCode);

I get this error

Code (CSharp):

1. Unity.Services.Relay.RelayServiceException: Not Found: join code not found ---> Unity.Services.Relay.Http.HttpException`1[Unity.Services.Relay.Models.ErrorResponseBody]: (404) HTTP/1.1 404 Not Found

Whereas if I do the exact same thing, but then also call StartHost(); and StartClient();

Code (CSharp):

1.             Allocation allocation = await RelayService.Instance.CreateAllocationAsync(3);
2.  
3.             string joinCode = await RelayService.Instance.GetJoinCodeAsync(allocation.AllocationId);
4.  
5.             RelayServerData relayServerData = new RelayServerData(allocation, "dtls");
6.             NetworkManager.Singleton.GetComponent<UnityTransport>().SetRelayServerData(relayServerData);
7.            
8.             NetworkManager.Singleton.StartHost();

Code (CSharp):

1.             JoinAllocation joinAllocation = await RelayService.Instance.JoinAllocationAsync(joinCode);
2.  
3.             RelayServerData relayServerData = new RelayServerData(joinAllocation, "dtls");
4.             NetworkManager.Singleton.GetComponent<UnityTransport>().SetRelayServerData(relayServerData);
5.  
6.             NetworkManager.Singleton.StartClient();

With this it works

So is that error intentional? Is Relay not supposed to be able to find the JoinCode if no connection is made with UTP or NGO?

 

Not sure but my guess is it works as intended and not an error, Relay is just that, relaying to something, so if no server is started it can't relay to anything ?
Still, interested in the correct answer from someone else !
