502 dunglas/mercure error intermittently. How to understand why?

For SSE I use the dunglas/mercure library. And periodically it throws out a 502 error. As I understand it, the client who got the error is disconnected from the ends. And how to understand what it lacks. There is enough memory on the server. The server is not loaded. What could be wrong?
