@crazycells Nope. Not unless you feel the urge/need. I was making more of a generic comment pointing out a potential pitfall. Cuz there's always a sub population of miscreants who will try to exploit the hard work of others for jollies, profit, etc. ✌
nginx must be on version 1.4.x to properly support websockets. Debian/Ubuntu uses 1.2, although it will work there will be a reduction in functionality.
Previously, in the same doc:
NGINX version v1.3.13 or greater
I'm not sure if that is just a sign of an outdated doc, or if there is actually some type of incompatibility (which apparently doesn't surface everywhere). All I know is that by reverting to 1.4.x, all functionality was restored.
