Did you check your Apache config?

[easy-HOWTO] Collabora, Ubuntu 16.04 with Docker and selfsigned | wildcard certificates

@victorbw, i found it out by myself. My Apache config was a little bit too restrictive: `Header always set X-Frame-Options DENY` After removing it, everything was fine Anyway many thanks!
