hi

I have the same issue with my C425. It was working fine for months and in December 2024 I did an firmware update as requested and since that my camera goes offline. I already restarted it 3-4 times but still facing the same issue. 
any suggestions?

  @Richie0414 Same problem. I bought 6 cameras of this type and some of them randomly go into "Offline" mode and you have to reset their HW from the button. So, if you are away from home, the camera is useless. And then you need it.  

 I noticed that 2 of them haven't locked up yet and those are the ones that have a different SW version, 1.3.11. The cameras that keep locking up lately are the ones that have sw version 1.2.23. If I try to upgrade them, it says that they are up to date.

Some answers here or should I send them back?

Thanks for sharing and my s.w version is also 1.2.23. I have reset the camera already 3 times it works fine for one hour and then if not online as before the camera is still not working I have to refresh constantly and nothing happen. As you no new software version is available. 
 

I'm very disappointed by the poor service of TP Link Tapo. My old Igeek is still working and I never had such issues...
