IPv6 Causing GMGN Key Rejection

GMGN only supports IPv4. If your network exit is IPv6, your key will be rejected, and the extension's diagnostics and popup will display "Your network exit is IPv6, and GMGN does not support IPv6." In this case, your key is most likely fine.

1. Disable IPv6 in your computer's network adapter settings, or disable IPv6 on your router.
2. Restart your browser.
3. Click "Check Now" in the popup on the extension icon to see if the error has cleared.
