@Nick1987 Hello,
Please confirm Tapo app is up to date first.
When "failed to pair " during set up, can you check router's client list ( may need to login router with the help of router support)and see if camera obtains an IP address from router successfully?
If camera obtains IP successfully but set up failed at last step, you could try some suggestion here:
- Turn off or lower Modem/ router Firewall settings that may block camera
- Check if there is any Advanced settings on router like access control/ parental control settings may affect the camera
- change router's DNS to 8.8.8.8/ 8.8.4.4
If the same problem, may I know the model of your router and your network topology? Who is your Internet Service Provider? Can you share with us a photo of the Error message? What is the model and IOS or Android OS of your phone, thank you.
