- What does ERR_INVALID_AUTH_CREDENTIALS mean?
- Chrome is trying to authenticate with a proxy or server using a username and password, but they were rejected. This usually appears on corporate or school networks that require proxy authentication, or when accessing a password-protected directory.
- Is this error dangerous?
- No. It just means your credentials were wrong or missing. No data was exposed — the request was blocked before it completed.
- How do I fix it?
- If you're on a corporate network, check with your IT department for the correct proxy credentials. If it's a web page asking for HTTP basic auth, make sure the username and password are correct and that Caps Lock is off.
