Can not established Websocket secure connection on Firefox

Question

I am stucked with Firefox. I could not make Websocket work on it. I use Tornado Websocket and I initialized it by code below:

app = Application([(r\'/mypath/         


        

Answer 1

I was pulling my hair out over this one for a while. I was getting all kinds of cryptic error messages depending on different web browsers, that all made it sound like it was something about certificate exceptions. I had already made exceptions in Firefox and Chrome,

It turned out I had a typo in my sub-protocol string in my Javascript!

Correcting the sub-protocol string made everything better. More information on WebSockets and using sub-protocol(s): https://developer.mozilla.org/en-US/docs/Web/API/WebSocket
