PancakeSwap Websocket Connection does not stay alive; closes after some time

[sadhippo]

Using this example for PancakeSwap: https://github.com/Nethereum/Nethereum.Templates.WebSocketStreaming/blob/master/ExampleLogsUniswapSyncSubscription.cs#L70

After 5-10 minutes, the connection closes and cannot be reconnected to.

Error message:
Nethereum.JsonRpc.Client.RpcClientUnknownException: Error occurred trying to send web socket requests(s)
---> System.Net.WebSockets.WebSocketException (0x80004005): The WebSocket is in an invalid state ('Aborted') for this operation. Valid states are: 'Open, CloseReceived'
