"Cannot access a disposed object" thrown OnClientDisconnect()

[Drakenfrost]

Hi there.

This error only occurs:

• on the server.
• when the client disconnecting is NOT also a host. Hosts stop perfectly fine.

The error seems to be caused by the base implementation of 'OnStopClient' called from the base 'OnClientDisconnect' method.

I am using the Multiplex Transport but currently only have Telepathy running.

I've tried first removing the client's ownership of all their owned objects as well as the player object. This did not help.

Here is the log:

Currently I just commented out line 324 in Telepathy.Server which has the trouble method 'GetClientAddress' as seen at the top of the stack above.

Please let me know what further information I can provide. Thanks in advance for any assistance!

I am also getting this issue with a regular .NET project and Telepathy, which I am using as a server app for my project.

When a client connects, the app receives the OnConnected call, but after that, fails.

It worked 4 months ago, now it doesn’t. Nothing changed in my project to make it fail like this.

Weird issue.

Oops. I figured it out - there was an early disconnect call in my project.
