I bought a TP-Link NC450 V2 camera last year for Christmas where it came with the v1.3.4 firmware. After updating it to the latest firmware v1.5.0 from the tpCamera app on my tablet, accessing the camera from my browser is giving me a warning that the security certificate is no longer valid. Furthermore, the camera keeps randomly disconnecting in the tpCamera app on my iPad until I restart the camera which solves it for awhile before the issue repeats itself.
I have tried downgrading it back to v1.3.4 back the process always fails. Browsing the forums shows that these disconnection issues are common for fimware after v1.3.4. There was a process to downgrade the firmware back to stock but all the links are not valid. Can a technical engineer help me downgrade back to v1.3.4 as I am using it to monitor my pets when I am at work.
