Hello Broke, thanks for answering.
> Is there any remote control switch on the camera setting of the Tapo APP?
I'm not aware of any remote control switch on the camera. Could you please explain me better what to look for ? Do you mean a physical switch on the camera ?
> Normally, the remote control was enabled by default after setup, and have you tried to reset the camera and set up from the scratches?
Yes I resetted it different times without result.
> Turn off the firewall on the main router;
Done without changes.
> Change the DNS server on the router to be 8.8.8.8/8.8.4.4;
I think this is the cause of the problem. My isp gave me a router already configured with his setting, giving me a reduced access as admin that doesn't permit me to change them. Very irritating.
I will tried the C200 on a different isp and I will let you know.
Thank you
