Authorization Failed for Credentials

Questions
1

I am working on the cloud version of n8n. This appears to be a known issue, but I have not found an answer and I have not heard back from support. My credential values are saved, but keep reverting back to an old value when I run n8n. I have cleared cache, uninstalled and reinstalled the template, deleted and added new credentials, but I am still having the same issue. The error is: Authorization failed - please check your credentials. Any suggestions?

What is the error message (if any)?

Hi Lori! This sounds like the credential auto-reset issue that’s been reported with Header Auth configurations. Based on similar cases from [community.n8n.io](Authorization failed - please check your credentials [item 0]) and [github.com](Authentication Credentials Reset Automatically in Header Auth Configurations in n8n · Issue #12596 · n8n-io/n8n · GitHub), try switching to a different authentication method temporarily (like adding your API key directly in the “Send Headers” section of your HTTP Request node) as a workaround.

If you’re using Header Auth and the credentials keep reverting to placeholder values, this appears to be a known bug where special characters in API keys cause the values to reset automatically. You could also try creating the credentials fresh in a new workflow to see if that resolves the issue, or contact n8n support again as this seems to be an ongoing platform issue that may need their direct intervention.
