hi Thanks. I temporarily created a wifi hotspot with the same SSID as main AP and got one of C500 to automatically attach to that. the version 1.1.3 was received and updated. But while previously no updates were being shown with the AP wifi. And indeed i realized that both C500 (one with 1.1.2 and another with 1.1.3) are online in the tapo app when checking on the same AP's WIFI, meaning the app sees them as online when connected locally via WIFI but not from outside when not connected to the AP Wifi.

I tried removing the AP from inbetween and connect the C500 directly to ISP modem WIFI, but exactly same behavior. This leads me to believe that there is something blocking the C500 connection to the tapo cloud at ISP modem level. This is not the behavior of the C210 which is always online.
I am trying to check firewall settings on the ISP modem and if any ports are being blocked etc., but i cant find anything meaningful. Can you suggest anything else that i can check?

Hi @Solla-topee 

I purchased Tapo C500 more than a year back and it has been working fine without any issues.But, post the recent firmware update (version 1.3.5) it started frequently going offline around once a week and need to be power cycled manually to be online again. I have tried resetting it and there are no change in the network side as well, everything remains the same and the connection is strong and stable. Could you kindly help to rollback to previous version or push a new firware to resolve the issue please. Thanks.

Thanks for your suggestion. The auto reboot feature has already been enabled and it is rebooting on a daily basis. But unfortunately, that doesn't seem to help.

  @Solla-topee I have Tapo C500 and since last 10 days, I have suddenly started facing frequent disconnection issues with my Tapo C500. Router is hardly 3-4 metres away from the camera.

Since last two years I have never faced disconnection issues. Suddenly I am facing this issue.

I have done a factory reset already and also formatted my sd card to see it works. But it didn't solve the problem.

The problem is that camera keeps going offline in the Tapo app. It comes online for maybe few mins and then suddenly it goes offline. Sometimes it doesn't come online until I manually turn off and on the electrical switch.

Can you please help asap?

It's really annoying. The camera is basically useless now.

Please solve my problem asap.

Below are the details of my camera:

Model: C500

Hardware Version: 1.0
