I am on workflow 2 of the level 2 course, the http request node keeps getting different errors in console tab.I have tried using different browser, incognito mode, restarting n8n (self-hosted) and repeated the process for header auth again using datasetURL and other credentials i got in my email. I’m stuck, please guide.
Looking at your screenshots, I can see you’re getting 404 and 403 errors, which suggests issues with both the URL and authentication. Here are the key things to check:
• **Verify the correct URL** - The course should provide the exact endpoint URL. Make sure you’re using the complete, correct URL from your course materials (not just `https://internal.users.n8n.cloud`)
• **Check your header authentication setup** - In your HTTP Request node, go to the authentication section and verify:
-
The header name is exactly as specified in the course (case-sensitive)
-
The header value matches the credentials from your email
-
No extra spaces or characters in either field
• **Test the credentials separately** - Try making the same request using a tool like Postman or curl with the same URL and headers to verify they work outside of n8n
Based on the [community.n8n.io]( HTTP Request Module Not Passing Authentication ) discussions, header authentication issues are common and often resolve by double-checking the exact formatting of your credentials and ensuring you’re using the correct authentication method.
