## Symptoms

- * Users fail to connect to internal sites via Mobile Access Blade's Reverse Proxy feature. Some sites return a 404 error code.
* Capsule Docs clients fail to connect to their server in order to display documents on client machines.
* A 'tracelog' debug output shows that the client request's 'Host:' header value appears in the request to the internal server instead of the server's host name.

## Cause

Mobile Access Reverse Proxy forwards wrong 'Host' header. Due to missing configuration, the gateway forwards the client request's 'Host:' header value to the internal server, instead of the server's host name.  
This is done for all requests by default.
