Thanks for your reply, have you ever tried to hard reset it and reconfigure the KC camera to give it a go?

What is the model number of it as well?

Please show us a screenshot of the greyed out page; and to do further analysis, please provide the mac address of the camera and your TP-Link ID.

Considering the security and privacy, you can send us these information personally via the message. 

Good day.
