Unable to connect to the ExtPlane plugin, why?

OK, so you've installed the ExtPlane plugin by extracting the contents of the ExtPlane.zip archive to the Resources\plugins folder of your X-Plane installation and started X-Plane. You've entered the first IP address from the 'Settings > Network' page but still can't connect. Does your PC have a firewall running? If so then you may need to add a firewall rule/exception to allow incoming and outgoing access to TCP port 51000. Unfortunately adding a firewall rule/exception is vendor specific so we can't list the steps here, but if you Google for it, e.g. "mcafee personal firewall add exception", you should be able to find the information online.
Note: On Windows, the plugin depends on the Visual C++ Redistributable Packages for Visual Studio 2013 (vcredist_x64.exe) which can be downloaded from Microsoft should you need it, https://www.microsoft.com/en-us/download/details.aspx?id=40784. If you see "X-Plane 11/Resources/plugins/ExtPlane/64/win.xpl : Error Code = 126 : The specified module could not be found." in X-Plane's Log.txt output, then you will need to install it.
Still can't connect? Another setting you could tweak is XP Remote's Connection timeout setting, 'Menu > Settings > ExtPlane > Connection timeout'. The default is 5 seconds, try increasing this to 20 seconds and then attempt another connection with 'Menu > Connect'.
