Tapo C210 internet video stream not working after firmware update
I have 4 Tapo cameras and after the last (automatic) firmware update on my 2 pieces of C210s, neither works anymore with internet video stream.
When I'm on the same wifi with my phone, I can open both cameras live video stream.
When I'm connected through internet, the Tapo app shows both C210s OFFLINE.
My other two (C200 and C320) cameras are just working fine.
Nothing changed on my router or at my internet service provider.
Reset and other user manual things are done.
These are DEFINITELY having trouble right after the firmware update last month.
I want to downgrade the firmware manually ASAP as this version IS FAULTY. Or provide me any other solution. What to do?
