performQuery did not handle the situation where the credentials had timed out or the cloudflare DDoS was re-requested.  Added a temporary solution by re-doing the log-in process.  It is a little slow, so users of this indexer will see a 20s delay.  I will find a way to improve that in a subsequent fix.
