I'm following the spec to a T. I never return an error code of 200; the only error code I return is 400 if I get a bad request. I'm not sure what your browser is doing. Make sure it's connecting over port 45695 and not port 80 (if it's port 80, that's some weird kind of javascript error).
Please note that I read this whole thing and implemented it exactly as it says: https://tools.ietf.org/html/rfc6455
I wrote the whole library; I know there's no place where I return a status code of 200. 101 and 400 are the only status codes in my library. I'll look around to see what edge is doing (probably something stupid).
It appears that I cannot connect from my PC (same error code as from my mobile phone, but it won't go away this time).
Before you ask, yes, I cleared cache. Yes, I logged out and logged back in. Yes, I closed and reopened the page. Yes, I tried reconnecting several times.
