Could the failures be caused by https://github.com/dotnet/runtime/pull/104251 @antonfirsov ? (cc: @simonrozsival)

unlikely @matouskozak .

       [Fact]
        public async Task Datagram_UDP_ShouldImplicitlyBindLocalEndpoint()
        {
            using var socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            byte[] buffer = new byte[32];

            Task sendTask = SendToAsync(socket, new ArraySegment<byte>(buffer), GetGetDummyTestEndpoint());

That tests sends data to random site that should follow default route and succeed. So this looks more like environmental problem to me. (or test design) If this is persistent we should investigate of the test systems have full internet access.

Thank you @wfurt for the investigation. I opened an infrastructure issue for it https://github.com/dotnet/dnceng/issues/3405.

The internet connection to the devices was restored. Closing.
