12c design view of JSF page fails to render with 'Loading failed Reason: Connection reset by server'

Question

When in the design view of a JSF page, the page never renders in JDeveloper 12c.  Instead I get an error message 'Loading failed   Reason: Connection reset by server'.  I traced this to a conflict with the port used by Cisco Anyconnect (5001) which seems to be something JDeveloper uses as well to render the page.  Is there a way to change the port used to render the page in design mode?  I could not find any settings in the preferences.

Hi Frank,
The proxy settings are set to use the system default proxy settings in JDev and I have not needed to change it when VPN'ed. 
The product that is in conflict is the 'AnyConnect Web Security Agent' (acwebsecagent.exe) which runs whether I am on vpn or am in the office - it is listening on port 5001 and that is the same port jdev64w.exe is listening to when rendering the page in the design mode.  I confirmed this using netstat -ab.  After  getting the conflicting program switched off temporarily, the design mode of the page was rendered within the IDE so that I could then drop components on the design surface.
Since I cannot get the Cisco product to listen on a different port, I am hopeful there is a way to modify the port used by JDev.
Thanks,
Sunil
