Websocket request not passing through WAF HTTPS traffic

We have a web server that sends websocket requests when being accessed. We are able to make it work through HTTP traffic, but when we got an SSL certificate to make it HTTPS, the websocket requests fails.

I have tried using Path-Specific Routing to enable the Websocket Passthrough but it still doesn't work. Am I just not using the Path-Specific Routing correctly or is it a limitation of Sophos for this case?
