What Is The Problem With Websocket And Self-Signed SSL Certificate

I have a project runs on intranet, so I didn't buy any SSL certificate or domain name. Instead, I created self-signed certificate. I have two layer one of which is web service/webs

Solution 1:

If someone else need an answer, I got it from here. As summary, the problem is about Firefox, not about other browsers. Main reason is that Firefox do not accept certificate of wss link, in fact it is also the same certificate for the first connection link start with https. Solution is to go to the link started with wss by chancing wss to https and accept privilege of that link, and everthing works fine :)
