1. No, the problem is that the "GetStatus" endpoint on the ONVIF API of the cameras is returning an "Internal Server Error 500". The live stream works fine, this is more related to the ONVIF API exposed by the camera in the port 2020.
    
2. It's not a specific app I'm using. I'm sending HTTP requests directly to the cameras OINVIF API at http://<cemera_ip>:2020 with the corresponding user and password. As I said, some of the endpoints of the API work as expected ("GetConfiguration", "GetNode", "GetCOnfigurationOptions", etc) but the "GetStatus" in particular fails with an internal server error. 
   The network diagram is very simple, both my cameras and my MacBook are connected to the same network (MB via wifi, cameras via ethernet) so there is a direct connection between them inside the local network. No firewalls, no VLANs no nothing. 
   ​​​​​​​
3. As of now, only 1 device watches the camera at the same time through the official iOS Tapo app. I want to integrate my cameras to https://frigate.video/ open source NVR. The integration is failing on the ONVIF connection which is why I'm debugging why it's falling and I've realized that the "GetStatus" endpoint of the camera's ONVIF API is not working properly as I mentioned earlier.

Hi.

Please, any update about this issue?

I have a C510w and same problem with API requests to endpoints "device-getcapabilities" and "ptz-getstatus"  (almost).

Thanks.

Hi,

Many thanks for firmware update. 

(device) GetCapabilities endpoint continues with same problem, but isn't problem because ONVIF docs says that the method has been deprecated and replaced by GetServices.

(ptz) GetStatus, now responds ok, but the "UtcTime" element should be returned in the ISO 8601 format.

Regards.
Andrés.

When I was contacted by the engineering team I mentioned the date format issue and they said they were going to evaluate if the change the format to ISO or keep it as is.

Hi  @Solla-topee

Please, any update about this onvif bad implementation?

Thanks.

Regards.
Andrés.

  @Andr3s12 I'm having exact same issue here where the python lib fail to parse the date `raise ISO8601Error('Unrecognised ISO 8601 date format: %r' % datestring)`
