   Steps to Fix

   1. Check your endpoint

   Go to the Azure Portal → your Computer Vision resource → Keys and Endpoint.
   Copy the exact endpoint shown there (it will look like https://.cognitiveservices.azure.com/).

   2. Verify your subscription key

   Use the key listed under Keys and Endpoint.
   Make sure you’re not mixing up keys from different resources.

   3. Update your code

   Replace both the endpoint and key in your code with the ones from the portal.

   Example (Python):

   endpoint = "https://.cognitiveservices.azure.com/"
   subscription_key = ""

   4. Test with REST API or SDK

   Try a simple request with curl or Postman to confirm the key/endpoint works before integrating into your app.

   5. Check region consistency

   If your resource is in West Europe, your endpoint must also be West Europe.
   Using eastus or another region will cause the error.

   Additional Troubleshooting & Resolution

   Quick Verification Steps:

   1. Test your credentials immediately using this simple Python script:

   import requests
   
   endpoint = "YOUR_ENDPOINT_HERE"  # e.g., https://westeurope.api.cognitive.microsoft.com/
   subscription_key = "YOUR_KEY_HERE"
   
   # Test URL
   url = f"{endpoint}vision/v3.2/analyze"
   headers = {
       "Ocp-Apim-Subscription-Key": subscription_key,
       "Content-Type": "application/json"
   }
   params = {"visualFeatures": "Description"}
   data = {"url": "https://upload.wikimedia.org/wikipedia/commons/thumb/1/12/Broadway_and_Times_Square_by_night.jpg/450px-Broadway_and_Times_Square_by_night.jpg"}
   
   response = requests.post(url, headers=headers, params=params, json=data)
   print(f"Status Code: {response.status_code}")
   print(f"Response: {response.json()}")

   2. Common mistakes to avoid:

      • ❌ Using <region>.cognitiveservices.azure.com instead of <region>.api.cognitive.microsoft.com
      • ❌ Missing the /vision/v3.2/ path in the endpoint
      • ❌ Copy-pasting keys with extra whitespace
      • ❌ Using expired or regenerated keys

   3. If still failing:

      • Check if your Azure subscription is active
      • Verify the resource hasn't been deleted or moved
      • Confirm you're not hitting rate limits (free tier: 20 calls/min)
      • Try regenerating your key in Azure Portal

   Resolution Status:

   The error code 401 is resolved by following the steps provided above. The issue was due to:

   • Incorrect endpoint format or region mismatch
   • Invalid or expired subscription key

   Samir1913 If the issue is resolved, please close this issue. For anyone else facing this problem, the solution steps above should fix the authentication error.
