Radio station works on LMS, fails on myqueezebox.com

I am trying to reduce my reliance on my local LMS. I mostly use a Squeezebox Radio to listen to internet radio so this is feasible.

I have one radio station that works as a favorite when I connect to my local LMS, but fails when I connect to mysqueezebox.com.

The radio station's URL is

http://opml.radiotime.com/Tune.ashx?...6dacc8e62fa646

The failure that I see on the small SBR screen is (approximately)

"Connection reset by remote host https://kclustream.callutheran.edu:8090/kclump3"

I have other radio stations in my favorites that work just fine using both my local LMS and mysqueezebox.com.

I am using the community firmware on my SBR; version: 8.0.1-r16881.

I use a wired connection on my SBR.

Any tips? This is a headscratcher.
