Created redmine issue http://projects.theforeman.org/issues/20578 from this bug
Created attachment 1313293 [details] irreproducible - All registered content hosts
Created attachment 1313294 [details] irreproducible - sub_status = valid
Created attachment 1313295 [details] irreproducible - sub_status != valid
I have not been able to reproduce this error. Furthermore, the related bug listed, 1406855, also seems to be irreproducible. I have attached screenshots of results. If this issue continues, could you please attach screenshots showing the attached subscriptions to the content hosts? The screenshots attached showing the problem seem to actually be correct (search for invalid showed an invalid host, search for valid showed valid host).
I confirm this works for me too. I believe what Djebran may experience is the 'temporary subscription', which renders content host 'partially entitled' (that would explain the filter behavior as well as the ability to enable the repos and install the packages from it).
This has nothing to do with CDN, when robottelo was updated to use non CDN repos many TestCases needed a care attention especially the subscriptions and errata ones. Plus that test was supposed working when merged. Fixed that test in https://github.com/SatelliteQE/robottelo/pull/5168 and close this bug as not a bug
