No door transactions coming into AMT

Transactions are not been sent by only one door.

Cause

If you have the AMT masking set correctly and the Door Editor has transaction defined for the reader entry or exit and there are no transaction messages showing up in AMT. Then one of the issues might be the Quick Poll (QP) is turned off for that DPU.
