I had to add the below to the firewall permission list of a Fritz!Box to allow watching NPO Start, the free Video on Demand service of the Dutch public broadcasting system:
npostart.nl assets.npo-data.nl www-assets.npo.nl start-player.npo.nl ccm.npo.nl images.npo.nl npo-drm-gateway.samgcloud.nepworldwide.nl time.akamai.com npo.prd.cdn.bcms.kpn.com
You can find the list on the page fritz.box/?lp=trafapp under Permitted websites edit.
