Websocket error wiht IIS

Hello,

I tried to establish an https connection with the IIS via reverse proxy. But I get the mistake again: Websocket! I kept to the instructions of freeky and the support.

Has anyone else the error or is it due to the new version?

Greetings throne

I asume you got connection, but you only got websocket error?
You have followed the guide about reverse proxy?
In inbound rules in reverse proxy, have you entered HTTP_SEC_WEBSOCKET_EXTENSIONS and value "true"?

yes in think so, and yes i get an connection!

Name                                                               value                        replace
HTTP_SEC_WEBSOCKET_EXTENSIONS                                             TRUE

and

Name                                                               value                        replace
HTTP_SEC_WEBSOCKET_EXTENSIONS             true                         TRUE

the same result --> Websocket error

Has nobody a Idea??

You have installed Application Request Routing 3.0, not 2.5?

If you have screenshots of your proxy and site settings, it will be easyer to diagnose.
