Client stops receiving messages #139
Description
I am connecting to a websocket and randomly my app stops receiving messages. There is no message that anything failed or that websocket was disconnected or server went away... Did anyone experiance same problems and is there a way to check if everything is ok (like ping) and to reconnect if server goes down.
@gngeorgiev, @beatgammit, @digitallumens, @dcarbone sry for ping but I see you are all maintaining your own forks... has anyone experienced similar issues and maybe created a fix that I can test/use?
