You could also try disabling "opportunistic suspend" [1]. To check your current Autosuspend policy run: # mcetool | grep -i suspend Set this to early: # mcetool --set-suspend-policy=early With this setting in place I've found websocket connections to be more robust. Websocket ping/pong work great and maintain the connection as long as you have network. This may have other implications including taking a minor hit in battery life so use at your own risk.
