This error appears periodically on my server:
SocketException: An existing connection was forcibly closed by the remote host.
at System.Net.Sockets.Socket.EndReceive (System.IAsyncResult asyncResult) [0x00012] in <09af50eda9a647268d2c4fcdf7fac506>:0
at System.Net.Sockets.NetworkStream.EndRead (System.IAsyncResult asyncResult) [0x0002a] in <09af50eda9a647268d2c4fcdf7fac506>:0
Rethrow as IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

At first, this error appears about 30 minutes apart, then after a few hours the server freezes and this error appears one after another from 10 to 30 times in a row.

There are no other errors besides this one, and no plug-in issues any errors. All my plugins have been updated to the latest version, all plugins are taken directly from the developers. I don't have any plug-ins using the network.
What could be the reason for this error? What kind of broken connection are we talking about here?

This with oxide?

This with oxide?

Yes, but as it turned out, this error is not the reason the server freezes. This error also appears periodically on the second server, which does not freeze.
I have not checked if this error exists on the local server with and without oxide. I'll check it out later. After studying some information, it was suggested that this error appears due to a loss of connection with the rust+ server, but this is just an assumption.
