I've never set that up on IIS, so I don't know what all is required to configure it to pass through correctly, but I suspect that IE11 is falling back to HTTPS and not attempting to use Websockets at all, while the rest of the browsers are attempting to use WSS. To confirm this you could try to disable Websockets pass-through entirely, forcing all browsers to fall back to HTTPS, and see if it works. If it does, then you have an issue with the IIS WSS configuration. -Nick >
