Websocket 302 (redirect) error

NGINX server {

}

The problem I’m having is that some computers and some browsers are being redirected when trying to get a connection to the websocket. When that 302 error shows up, the '/*' routes has been activated! This route redirects the user to the login page as you saw in the redirect response.The websocket upgrade request is turned into an ordinary http request somehow, somewhere! This seems to be where the problem is. What can be causing this?

You may need to update

if ($sslprotocol = "") {
rewrite ^ https://$host$requesturi? permanent;

}

to this

if ($https = "") {
rewrite ^ https://$host$requesturi? permanent;

}

I haven’t seen the use of $sslprotocol before in this context and wasn’t able to find anything through a google search.
