During the application setup, I installed the CCM application firstly but with a wrong URL.
Then delete the CCM application and try to resetup it, but it report CRJAZ1720E error, as following,

it seems is caused by my first installed application, however, I already deleted it. but why it still report error when re-register this application? how to resolve this? thanks a lot for your
help.
