Q:

Secured WebSocket connection not working in FireFox and Chrome in MAC OS?

I am having two applications one in server and another one is client application. In server I am creating webSocket and in client I am creating we webSocket client.
Here I am getting Error (FireFox and Chrome) while creating webSocket client (in safari it is working fine).
I followed HTTPS configuration step  which is in the link
 WebSocket connection to 'wss://localhost:8443/ws/v1/user/userId=user1' 

failed: Error in connection establishment: net::ERR_CERT_COMMON_NAME_INVALID
connect @   
web-socket.ts:53
    setTimeout  @   
web-socket.ts:86

A:

Firefox and chrome  will keep on giving you error until you open up a separate tab and do try hitting URL https://localhost:8443 and Confirm Security Exception. Then try it will work.
