If this occurs on all the cameras, this might be related to router settings or wireless environment. Here are some tips that you could give it try :

• For a test, temporarily  turning off mesh for smart home devices only (if mesh has this option) or turn mesh off for a test
• Check if there is any Advanced WiFi settings on main Router turn off to help isolate the issue: 

-  Band steering（Smart Connect）/ Channel optimization（Wi-Fi Optimizing）, those settings may force device on a different band or change channel and may cause some trouble for smart devices, 

• Ensure Tapo camera has good Wi-Fi signal as guide here:

• Confirm kasa app and camera firmware are both up to date 
• When issue happen, connect phone Home Wi-Fi network force close and reopen APP, can you access camera in Local network?
