BlueSolar 75/10 MPPT shuts down when I plug in VE-Direct Cable

I typically leave the VE-Direct USB cable plugged into my charge controller so I can easily plug it into my Android phone and monitor the battery and charge when I'm camping. This weekend I tried to plug in the phone and couldn't get it to find the device. I also was not getting any power out of the battery.

When I unplug the cable from the charge controller, I get power out of the battery again and the lights on the charger show that it is charging. But as soon as I plug the cable back in, I lose power and both (blue and yellow) lights on the charger illuminate solid.

Any ideas on what is wrong?

Can you make sure that the pins inside the connector of the charge controller are not bent and make contact with each other ?

Because this reminds me of a short on the data bus

Also what Cable and USB to serial you use to connect your charge controller to your phone ?

Thanks
