Unfortunately I have the same error, but just to make sure:
before this addition I only had the following in my apiserver.conf

auth {
    # Fixed users login credentials
    # No other user will be able to login
    fixed_users {
        enabled: true
        pass_hashed: true
        users: [
            {
                username: "user.name"
                password: "blabla"
                name: "User Name"
            },
        ]
    }
}

and now after the addition:

``...

thank you so much

it seems that config.skipFileServer : true and that's why he skips the convertToReverseProxy(url)) .
where can I change that value?

I think yes

WebApp: 2.1.0-664 • Server: 2.1.0-664 • API: 2.32

I mainly have problem with debug samples as now i manage to see some plots that were created with plt.imshow() . But I still don't see any kind of debug samples (images, audio, txt etc.) with the same 401 error.
So it's weird how some images from the file server can be accessed while other files can't.

It works!!!

When I ran the following code:

task = Task.init(project_name='DevOps/debug-subproject', task_name='test-task6')
task.logger.report_media(
    title='audio', 
    series='tada', 
    iteration=1,
    local_path='./audio-sample.mp3'
)
task.close()

and then in the UI when I look in developer tools I see that it tried to access:

do you mean I should add the following to /opt/clearml/config/apiserver.conf :

auth {
    cookies {
    httponly: true
    secure: true
    domain: ".my.domain"
    max_age: 99999999999
  }
}

based on these docs

from clearml import Task
    def _get_user_mapping(self):
        # type: () -> dict
        """
        Get mapping from user IDs to usernames
        """
        res = Task._get_default_session().send_request("users", "get_all")
        if not res.ok:
            print("Warning: Cannot get list of all users, will use user IDs")
            return {}
        all_users = res.json()["data"]["users"]
        return {d["id"]: d["name"] for d in all_users}

no didn't use that,
Do you suggest the following?

    cookies {
    httponly: true
    secure: true
    domain: ".my.domain"
    max_age: 99999999999
    samesite: Lax

  }

tried it, nothing has changed.

Where can I find it?
if you mean /opt/clearml/logs/apiserver.log then it logrotates every one hour so I'm unable to get those logs right now unless I restart the service, is there another way to check that?
