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I'm not sure if that is just a sign of an outdated doc, or if there is actually some type of incompatibility (which apparently doesn't surface everywhere).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.
Hi all, today I just installed a cloud version and I can't change files myself. Faced with the same problem. I've changed the theme back to Persona and now can open no frontend nigher backend. It forwards me to the nodebb website and shows this message:
