it64 i will use some Guacamole REST Services in my awareim. i think my problem is the missing Content Type "application/x-www-form-urlencoded" in the request body in awareim https://github.com/ridvanaltun/guacamole-rest-api-documentation/blob/master/docs/AUTHENTICATION.md#headers
aware_support Make sure you use the latest build. In this build if you add your own Content Type header Aware IM should respect it.
