I received an unexpected error trying to login at firefox sync. Seeing at console I found: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.accounts.firefox.com/v1/account/login?keys=true. (Reason: CORS preflight channel did not succeed)."

How can I solve that?

Thanks

When I try that link by clicking it, I get a 503 server error, so maybe that's the real problem that needs to be addressed before Sync users can log in.
