Hi, I was trying to connect a ptz camera with API on python. But I faced a weird problem. The API can see the camera and return the hostname. But when I try to return the media profile (GetProfiles()) there is an error appears:
..
zeep.exceptions.Fault: Unknown fault occured
..
onvif.exceptions.ONVIFError: Unknown error: Unknown fault occured

Furthermore, the same code works well on different camera
('good' camera: DH-SD59232XA-HNR, Firmware: V2.810.0000017.1.R.P9.3217.UN.NR).
I'll be glad if anyone can help.

Camera: DS-2DE7A432IW-AEB
Firmware Version: V5.8.0 build 230519
WEB: V5.1.0_R0101 build 230213
ONVIF : 19.12

python 3.6
zeep==4.1.0
onvif-zeep==0.2.12

Code:

from onvif import ONVIFCamera

ptz_username = 'xxx'
ptz_password = 'yyy'
ptz_ip = '-.-.-.-'
ptz_port = 80

wsdl_folder = '/usr/local/lib/python3.6/site-packages/wsdl'

mycam = ONVIFCamera(ptz_ip, ptz_port, ptz_username, ptz_password, wsdl_folder)

resp = mycam.devicemgmt.GetHostname()
print(f'My camera`s hostname: {str(resp.Name)}')

media_service = mycam.create_media_service()

media_profile = media_service.GetProfiles()[0]

The error message:
My camera`s hostname: Hikvision
<onvif.client.ONVIFService object at 0x7f832d7320>

During handling of the above exception, another exception occurred:

You are calling it the wrong way.
This should work:

media_service = mycam.create_media_service()
resp = mycam.media.GetProfiles()
print('Profile data: ' + str(resp))

Hopefully this helped :)

@MaxKKuznetsov have you fix this error? Have the same problem.
Proposed solution unfortunately does not work.

I have the same issue with Hikvision PTZ Kamera (DS-2DE2A404IW-DE3)

I digged a little in the soap requests. The issue might be because of a 401 (Unauthorized) response of some requests e.g. GetProfiles():

<html>
    <head>
        <title>Document Error: Unauthorized</title>
    </head>
    <body>
        <h2>Access Error: 401 --
            Unauthorized</h2>
        <p>Authentication Error: This onvif request requires authentication
            information</p>
    </body>
</html>```

@MaxKKuznetsov & @gitwojtek

I resolved the unathorized issue with the suggested solution in this post: https://ipcamtalk.com/threads/onvif-problem-with-hikvision-dvr-the-http-request-is-unauthorized-with-client-authentication-scheme.42433/post-747891

Just set authentication to "digest+ws-username" or "digest+wsse" token (In camera settings - configuration / network / advanced settings / integration protocol) and make sure your time is accurate.

So this is a Hardware/Firmware setup issue not an issue with python-onvif-zeep. Please confirm, then the issue can be closed.
