auth api: Access denied

[reclock]

Ask a Question!

images: portainer-ce:2.32.0

The portainer auth authentication interface will report an error {"message": "Access denied", "details": "Access denied to resource"}, but it does not always occur. Why??

Can you please provide detailed steps on when you see this as well as screenshots?

You are also on an older version of Portainer, please update and let me know if you still see the issue

I'll upgrade the software version first

now image is : portainer/portainer-ce:2.33.6
code:
portainer_api_addr = "http://192.168.6.105:9000"
auth_url = f"{portainer_api_addr}/api/auth"
auth_response = requests.post(auth_url, json={"username": portainer_user, "password": portainer_password})
if auth_response.status_code != 200:
raise Exception(f"Failed to authenticate with Portainer, status_code: {auth_response.status_code}, response: {auth_response.text}")

error:
raise Exception(f"Failed to authenticate with Portainer, status_code: {auth_response.status_code}, response: {auth_response.text}")
Exception: Failed to authenticate with Portainer, status_code: 403, response: {"message":"Access denied","details":"Access denied to resource"}

NO，192.168.6.105 is serverIP, NO porxy.

And in most cases, it is successful, with occasional failures. After a failure, simply restarting the Portainer container resolves the issue
