Prevent sending requests that are known to fail

In case it's still unknown if auth is set up on the server, only the initial request to detect this should be sent. Since all other requests will also just fail, they should be blocked until the auth initialization is completed.

While the access token is getting refreshed, no request will succeed since the access token is expired; thus, they should not be sent.
