I ran into a problem with the long running web app subscribing for the SSE stream. So far I cannot easily reproduce this since this issue seems to appear only after many hours. The web app reconnects to SSE stream if the network connection is lost and back. However, I think that maybe the app does not reconnect properly if the SSE stream is disconnected on the server site.
Maybe someone already know if the particle cloud has any timeouts for the long running connections to the SSE stream?
