SITL Quadplane does not connect - SOLVED

Quadplane times out when trying to connect. Every other model connects, plane, copter, rover, etc. Its just Quad plane that does not. I’ve tried updating to the latest beta firmware, same thing. I’ve uninstalled and reinstalled, it worked once but it would not let me takeoff at all. Help!!

Attached is a screen shot of the error.

OK, so i used the “wipe” feature in SITL and it loads up fine. So it must be something in the quadplane config files i uploaded. I’m on 4.1.2, any ideas on what param it could be? Here is the config file.
Quadplane.param (21.0 KB)

Solved…It was Serial Protocol 1 and 2. They were both set to 1 when they should be set to 2.
