Media player "full album" button broken

[evsmith]

In several pages (e.g. here: https://imslp.org/wiki/6_Violin_Sonatas ... Sebastian)) I can listen to individual pieces from an album in the commercial recordings section, but if I click on the "full album" button the the recording never plays.

I investigated this a bit, and it seems that for individual works the URL is like this:
https://stor.imslp.org/naxos/albums/TRO ... 387824.mp4

But for the whole album the URLs are like this:
http://s6.imslp.org/naxos/albums/TROY16 ... 387820.mp4

...which fails with ERR_CONNECTION_REFUSED.

Apologies if this has already been reported - this is the first time I've posted here! Let me know if I should give more details.

Some relevant details I should have included: I'm using Chrome Version 72.0.3626.109 on Ubuntu 18.04. I also get this problem on Firefox though.
