Problems playing nrk.no podcasts

Platform:
duet receiver, firmware version 77
logitechmediaserver 8.0.0~1605342997, running on debian 10.7 "buster", amd64

My duet receiver won't play the entries of this podcast
http://podkast.nrk.no/program/mitt_liv_med_hund.rss

The /var/log/squeezeboxserver/server.log show this from my attempts at playing episodes in the podcast:

Opening one of the .mp3 URLs in a browser on my laptop plays the episode fine.

Using wget to download one of the episodes on the computer running LMS, also worked fine:

Any ideas what I could try to troubleshoot this further?
