I have looked everywhere and can find no information on this. Any assistance would be appreciated.
Are you using the original configuration of your Workbench instance?
Uncheck "Check for Latest Version" in the configuration. The Workbench source code is hosted on Github and the application uses a tag URL to check for new releases. (If this check used to work: Does your application run from the same IP? If not, does a firewall block the application from making calls to Github?)
