Third Party Socket Exception with Playfab mp example when updating Mirror from 43.3.1 to 43.4.3 (Telepathy)

Edit: Seem to have found a solution. Turned off autobuild and changed some of the NeworkServer calls to NetworkManager calls instead. Thanks to Solias on the Mirror Discord.


I'm developing my networking game flow based off these two projects using Unity, Mirror, and Playfab.

https://github.com/natepac/playfabmirrorgameexample/tree/master

https://github.com/PlayFab/MpsSamples/tree/master/UnityMirror

I'm using a game configuration object in this version. If there is no IP in the configuration, I call PlayFabMultiplayerAPI.RequestMultiplayerServer and add the IP and Port to the network manager, then connect. I get the correct information, but seem to be immediately disconnected (client times out). When I use the same information directly in the configuration and skip the call to RequestMultiplayerServer, I connect and have no issues.


I started testing locally using the Playfab LocalAgent. I found that I'm getting socket exceptions after changing to certain versions of Mirror. In the server build, the network manager starts up, then the example code calls NetworkServer.Listen() (which would be the second time it's called) and then I get the exception.

This is the second call :

Code (CSharp):

1.         public void StartListen()
2.         {
3.             NetworkServer.Listen(base.maxConnections);
4.         }

Edit: At Mirror version 43.3.1, Telepathy works fine, but KCP gets the socket exception, once I get to 43.4.5, both Telepathy and KCP have the issue. The main change between those versions seems to be the code involving calling Telepathy.Client and Telepathy.Server

Code (CSharp):

1.             // create client & server
2.             client = new Telepathy.Client(clientMaxMessageSize);
3.             server = new Telepathy.Server(serverMaxMessageSize);

I'm assuming that KCP probably already had similiar changes prior to 43.3.1, which is why it gets the exception and Telepathy doesn't. I'm not really sure how to fix the example code to get it to work. I've tried making the second call only if NetworkServer isn't active, but that didn't help, nor did taking it out entirely (well, I avoided the socket exception, but it didn't work properly otherwise).

I've attached the two versions of the telepathy files in the comments section below.

Any help would be greatly appreciated

How did you solve it?
