@David-TP 

Thanks for the reply. Its just an empty client list

I have internet access and I can log into https://tplinkdeco.net/ and see the list of clients connected, but the mobile app is not able to retrieve the client list.

I was using OpenDNS FamilyShield DNS IP addresses and thought that was blocking the request to get the client list so I switched back to my Xfinity DNS but the problem is still there. 

It was working fine with the exact settings I have now.

I have rebooted the router many times as well as unplugged it from power.

Are there logs on the router that can show all requests going to/from it?

.

  @David-TP , any thoughts on this issue?

When I try to view the client list on my phone, is it going to a cloud service to get the data and that request is failing? Or is it trying to get data from the router itself? I can see a list of clients when I log in to the web version but even that looks like an outdated list.

Without the ability to view clients/connected devices the Parental Controls are useless and I'd have to return this product for something else.

Any help is greatly appreciated.

Thanks.
