Hi, are you still having the same issue now?

If yes, can I have a picture of the error message on the Kasa APP?

By the way, what is the model number of your home router?

Thanks a lot.

Hi, thanks a lot for your time and patience.

May I know the model number of your smart Wi-Fi switch, like HS200, HS210, HS220?

After that, please refer to the following suggestion:

1. if it is iPhone, please enable the local network for Kasa App, such as https://www.tp-link.com/en/support/faq/2937/

2. please make sure there is no VPN enabled on the smartphone;

3. if possible, please test on another smartphone to have a look;

Thank you very much and wait for your reply.
