    I am running a headless linux build in a ubuntu server. The max connections property of network manager is set to 4. After running successfully for a few hours the server build starts refusing incoming connections.
    The server logs show this warning: Warning: no free slot for incoming connection.
    However at that time no player is connected to the server not one on any of the 4 connection "Slots". This is also showin in the logs because right before this error it says.
    Connection {4} timing out etc etc.
    and abve that the time out of the other connections.
    This is really frustrating and any help debugging would be really appreciated.

    Probably a bug, but Unet was deprecated a year and a half ago. Plus the NetworkManager and the rest of the HLAPI has had virtually no development (outside of Mirror) for a few years prior to that. So don't hold your breath for a fix.

    We're facing the exact same issue in Unity 2020.3.10f1. Does anyone have any insight on this issue?
