Fixed crash after the RSS server fails to start due to missing permissions #246

Closed ribbons closed 3 years ago

ribbons commented 3 years ago

If the RSS server fails to start due to missing permissions a user-friendly error message is displayed. However, once this is closed the application crashes due to the following unhandled exception:

System.ObjectDisposedException: Cannot access a disposed object. Object name: 'System.Net.HttpListener'.
   at System.Net.HttpListener.CheckDisposed()
   at System.Net.HttpListener.BeginGetContext(AsyncCallback callback, Object state)

This appears to be caused when RssServer.Start() is called from the main form after the listener fails to initialise correctly in the RssServer ctor.
