You need to do a reread for the worker processes after you edit the supervisor.conf - you should also check all your log files. I found quite often if I left a process alone even after the timeout, that it would finish in the background some time later (as much as 20mins), but if you close the screen, or click the OK, it seems to terminate.
I would look at the node-socketio.log and see if there’s anything there. In my case it was searching for another IP address (see this post) but I am yet to solve it
