Hello   @MartinNovotny 

Thank you for the feedback, if Tapo camera is accessible in the home Wi-Fi network but offline remotely: 

1. Please reboot Tapo camera first (Tapo APP> tap  the ' wheel' icon on the right top of Live view page> Camera settings> reboot tapo camera )

2. Try some tips in  the below guide Case2 : 

What should I do if I can't view the Tapo camera?

3. Please connect phone to a different Wi-Fi network, or test when phone using mobile data from a different SIM card company. (this is to see if it's related to a certain ISP or SIM card company )

You may also factory reset the camera and reinstall it , or connect it to a Guest Wifi network and see if that makes any difference.

If the same, can I know the model of router and network map. e.g. ISP x-  router Archer C7<Wireless>tapo C200. 

Please help collect the camera log and share the log file with us. How to Get the Log of Tapo Camera? Thank you. 

  Hello @MartinNovotny 

I'd like to create a support email for your case, TKID220901700 kindly check your email inbox later. 

If you can not access the camera remotely (when the phone is on mobile data) it's can be due to that the camera is still offline on the cloud (due to router DNS, firewall etc.), or it's the phone itself ( due to mobile SIM card provider) 

• Try to change router DNS to 8.8.8.8, save the settings and reboot camera. 
• Make sure you have test on a different phone or phone using a different SIM card provider or you test a different outside network on the phone  

If still the same,

1) may I know the model of router, and the network topology:e.g 

ISP-modem - router Archer A7<Wi-Fi>camera works fine 

ISP-modem - router Archer A7<Wi-Fi>camera, device 

2) Please help collect the log file of camera, attach the log file here  3)   share the MAC address of camera via private message.
