SSE Events Timeout

My events stop being received after an extended period of time (using Cloud API event SSE endpoints) - but the connection does not fail out or close... is there a limit being enforced on the backend for how many events can be received in a certain timeframe?

There is no limit to the number of events that can be sent over a SSE connection or time spent connected.

This is rate limit for establishing new TCP connections to the SSE endpoint.
