If Fiddler has been used to proxy connections from Essentials or Essentials Manager and is no longer running, you will get an error when trying to launch sites:
Exception has been thrown by the target of an invocation. Unable to connect to the remote server No connection could be made because the target machine actively refused it 127.0.0.1:8888
This error may be suppressed if Essentials has cached the remote content of a site.
The solution is to remove the elements that are directing Essentials to use Fiddler. These elements are found in the web.config files for Essentials and Essentials Manager. A typical entry would look like:
<defaultProxy> <proxy proxyaddress="http://localhost:8888" bypassonlocal="false" /> </defaultProxy>
but there are variations on it.
