Hi,

can confirm the same issue. After a successful http request there is no upgrade to the websocket connection and instead socket-io downgrades to simple http polling. Had to go back to v1.7 for now.  
I believe this could be also a related issue: [How to make WebSockets work with Traefik 2.0 (setting up Rancher)](https://community.containo.us/t/how-to-make-websockets-work-with-traefik-2-0-setting-up-rancher/1732)
