I’ve got my first websocket system set up and its working well but it is ignoring the reconnect delay and just doing it at 5000ms.

private static readonly Random _random = new Random();

I’ve tried adding random delays between 5000-30000 but it always stays at 5.

I have about 2000 clients staying connected at a time, so if the server goes down and all 2000 try and reconnect I'm concerned there will be issues.

• c#
• socket.io
• reconnect

• You are not using randomDelay in the code. All you are doing is outputting the value. The delay is always set to ReconnectionDelay = 10000, A socket retries to connect up to 3 times at 5 seconds intervals and that may be why you are seeing a retry every 5 seconds. – jdweng Commented Mar 14 at 13:02
• Thanks @jdweng that was intentional in case it was having issues with the variable. It wasnt even waiting the 10 sec just 5 though. – Glenn Angel Commented Mar 15 at 11:04
• Websocket is using TCP for the transport method and there is a delay in TCP. See stackoverflow/questions/63675902/… – jdweng Commented Mar 15 at 11:14

I found the answer which i wasnt aware of. There is a MaxReconnectionDelay which is default at 5 sec.

What was happening is that since my delay was random + 5sec, it would just default ot 5 sec.

I have changed the max delay to 45 seconds now (yes very long) and my random reconnect delay is set to between 5 and 45 secs. This is now working!!
