Erizocontroller web socket error

We have been running our application as https://url/app for quite a while
without problems when erizo.js makes calls to the erizocontroller.js
server. We updated Licode to the latest branch and now our app, in
erizo.js, generates this error:

[blocked] The page at ‘https://appurl.com:3004/app#
https://4vision.com:3004/dlspdemo.html#’ was loaded over HTTPS, but ran
insecure content from ‘ws://appurl.com
:8080/socket.io/1/websocket/N37A0V-l4SW_rVqFYBNY
http://4vision.com:8080/socket.io/1/websocket/N37A0V-l4SW_rVqFYBNY’: this
content should also be loaded over HTTPS.

Uncaught SecurityError: Failed to construct ‘WebSocket’: An insecure
WebSocket connection may not be initiated from a page loaded over HTTPS.

How do we fix this?

Thanks
