Hi @duynguyenKHTN, thank you for letting us know about this issue.

To better understand the nature of the issue, can you provide us the transport protocol you are using for your project?

If your project is not using UTP (com.unity.transport), can you try it with UTP and see if you are still encountering this issue?

Same issue. I played as a client for about 10 minutes and getting this error with the following errors after:

The behaviour after a bug appears is the following: client can sent all request to a server and server recieves it. But the bugged client does not recieve any messages

com.unity.transport version 2.3.0 has released today that I think should have a fix for this issue. A new release for the 1.x line of com.unity.transport should be out soon as well, I'll post again when that is out in case you can't or don't want to update to 2.3.0.

Can you retest and confirm for us?

michalChrobot commented 1 week ago

It should be fixed in com.unity.transport 2.3.0 as well as in 1.5.0. If after updating to one of those versions it will still not work correctly let us know, otherwise we will be slowly closing issues related to this bug. If you will still experience this problem feel free to reopen the issue.
