I think the reference for the Troubleshooting page should be more narrow so
that people only see the URL only for the cases we give specific advise for.
Otherwise I assume they will just ignore the page if they do not find the
advise for other errors.

Other idea would be to give reference to the article when the actual CSR is
generated - as a heads up.
