TCP Zero Window occurs on iOS only (Can't receive packet)
My game sometimes occur TCP Zero Window only on iPhone.
When it occured, there is no problem with sending data. But app can't receive any data.
I checked packets with Wireshark when it occured, tcp window is going down suddenly, and it became zero. As it become zero, app can't receive data.
I'm using Unity 2018.4.8f1.
I used System.Net.Sockets.TCPClient.
It only occurs on iPhone not on Android.
But my iPhone11 haven't occured this situation, but my friend's iPhone12 occurs very frequently.
Is there anybody having such situation?
