Problem with a specific stream

I just tried to play some of the m3u and pls streams from this site https://www.deluxemusic.tv/radio.html but this won’t work. Kodi gives me

The m3u for example contains https://deluxe-radio.mivitec.net:8443/0001 – maybe kodi can’t play m3u/pls streams from https sources or is the port problematic?
(No proxy nor VPN used. m3u/pls are playing fine when played via VLC)
