Currently, if the application can't get a token from the ArcGIS Server endpoint (on ROK Tech), we only show a message to the effect of "couldn't get the token, sorry". It doesn't attempt to retry the request.
Since the problem is fairly rare, a short term solution is in cfe8ef725ca65a931168aa6009755fc687f0b015, which advises the end-user to refresh the browser window. This almost always works.
The real solution of course is to attempt to retry acquiring that token using a randomized and exponential back-off and retry approach.
