Hello @Patatin 

Thank you for your valuable feedback. 

Do you mean the cloud videos could load correct when phone is on LTE mobile network, but reports ' refresh' when phone is connected to home Wi-Fi network?

- confirm Tapo APP &  camera firmware is up-to-date

- try a different phone if you got one 

-  check if router firewall block any tp-link domain/ request of camera, try to adjust router firewall settings 

Can you help confirm some case details here  1). a photo of error & a video link showing the issue 2). router model and network topology .e.g ISP XX-- Router Archer C7 <wireless>tapo camera 3) model of phone and its IOS or Andriod version ; tapo app version 4) please share the mac address of camera by private message , thank you 

Hello   @Patatin 

Got the information you shared! 

• To help isolate the issue,  for your network :  ISP router - Deco Mesh system, please  bypass the Deco and connect one camera directly to ISP Wi-Fi router and see if the camera could access the cloud videos? 
• May I double confirm the ISP and network map: e.g ISP Orange Livebox router model XX --Deco M9 --Deco M9 <wireless >Tapo
• You could attach a photo showing the issue on the forum or on the support email below. 

The issue seemed to  relate to the home network environment, it is possible that  ISP or routers blocked the port/ service that camera using to access cloud videos, to better assist your case, we would like to escalate your case through support email  TKID220303830, please check your inbox, thank you. 

  @Patatin Glad to hear that camera Cloud videos works fine right now after you reinstall the cameras 

Thank you for updating solution here in the community~
