Local Universe - Unexpected down stream http error: GET 503



I try to create a local Universe with a selected set of Universe packages.
I clone the Universe repository, build universe-base and bla bla bla....
everything went well, the image was created and then I copied it to the
master dcos, load it and bla bla...all as described in the documentation.

Then I run the dcos command to add repo and of course I can see the
repository on the UI dcos but when I try to see packages an error occured:

"Unexpected down stream http error: GET http://xxxxxx:8082/repo 503
You can go to the Repositories Settings page to change installed repositories."

...of course same thing if I try to use dcos cli.

Any help would be appreciated!
