CORS after a long inactivity in the chat

Question

I have been inactive in the chat for more than an hour since the connection was initialized. After I started sending requests to getstrem (receiving messages, for example) and I get an error (I attached a photo). Although connection is still active andevent health.check comes to me. This occurs only after a long inactivity. What could be the problem?

Answer 1

I have found a solution. When initializing the connection on my own backend side, I create a token and specify the expiration date for it. If not specified, then by default this value will be null (infinity)
