Aurora R10, how to fix error code: 2000-0716?

I opened the main body of my Alienware Aurora R10 Ryzen Edition to clean the dust on the fan. Put everything back and the computer is working fine except this error code.

Version: Build 4400.16 UEFI ROM

Error Code: 2000-0716

Cables - Check the following cable, () Alert Front I/O Cable Failure.

Not sure which cable that is? How do I fix it?

Thanks!
