The more likely culprit is my 10+ year old Ideal crimper which I use every day.
That is most likely the issue here. We had same problem ( although not a monoprice connector ). I noticed it when UNIFI contrloller was was showing 100Mb connection to the switch, instead of 1gb. Getting a new crimper solved our problem.
