Youtube referer as Direct Entry

Hi all,

I just found a problem with my referers…YouTube doesn’t appear in Piwik !
By making a test, I found when visitors come from YouTube, they are considered as Direct Entry … and not as Website

Do you know how to fix the problem ? Or how can we explain it ?

Thanks in advance

IS it because the URLs are HTTPS maybe?

Otherwise see: Visits from search engines or campaigns are not recorded, Piwik shows "There is no data for this report" for all Referrers reports. - Analytics Platform - Matomo
