Simhub Webpage JRT Dashboard

Recently my JRT Dash stopped working on my GSI wheel.  I use "Webpage" display and directly connect to the IP/html file for the dashboard.  It seems to partially draw and then stop.  I am not sure if this is a JRT issue or Simhub but I wanted to "clear cache" if possible on simhub web display but not sure at all how to do it.  Is there a way to clear the cache?

Thanks!
