The page refresh was not being triggered by the websocket when using ngrok on Jacob and Vladimir's computers. It could be ngrok or it could be the fact that they were on different wifi or merely that they were on different machines. Try to reproduce the problem by using ngrok with a different computer and on a different IP address I.e. using a VPN. Then see if there is an error with the websocket connection in the browser console. It may be a CORS issue.
