CF 230

Developer get error above for an existing application.
I check another application, same error. I deploy a new application successfully, same error.
bosh vms look fine. bosh cck looks fine. cf routes, yes routes are there. No errors.

I created a new shared domain successfully. Deployed another app specifying that domain, successful. Pull up the url and get the error in the subject.

What happened to the existing routes? Check of the router logs show 404.
Where to look next to find out where the routes have gone??

(This is a different environment than my other issue. )

Confused,
Tom
