Is this a brand new install of Operations Dashboard for ArcGIS or did you upgrade to a new release?
If the latter, was Operations Dashboard working previously?
I don't suppose you've tried uninstalling, then re-installing the software?
Some other related threads that have suggestions to help troubleshoot:
Hope this helps,
I actually thought that could be an issue. So I went to machine which had never had it installed and did the download/install. Same problem. I will look at your links though.
