What does this problem usually mean?
Authentication errors usually mean the application is not sending a valid credential in the way the current provider API expects.
What to check first
- 1
Confirm that the application is loading the intended credential from the intended environment.
- 2
Do not paste the full API key into logs, screenshots or support tickets.
- 3
Check whether the key was revoked, replaced or belongs to a different environment.
- 4
Verify the API base URL and provider configuration.
- 5
After correcting credentials, test a minimal API request before the full application.
Important: verify the result
Change one thing at a time and repeat the same test afterwards. A successful command is not proof of a fix; verify that the original failure can no longer be reproduced.
Never include full API keys, passwords, seed phrases or private keys in screenshots, logs or support requests.
Note: Provider features, limits and versions can change. For version-specific questions, always verify the current vendor documentation.
