RSS Reader unable to open one feed

[G. Danton]

I am using VLC to listen to podcasts, and something weird is happening with one (and only one) feed I have. If I click any track in that feed, I get an error. VLC reads every other RSS feed fine, and any other RSS reader I check reads this podcast's one fine. For some reason it's the specific interaction between this one feed and this one player. Here's an example error:

Your input can't be opened:
VLC is unable to open the MRL 'https://pdcn.co/e/http://feeds.soundclo ... -leong.mp3'. Check the log for details.

the more verbose version I found in messages is too long and won't let me post, so I trimmed the first part:

If I copy and paste that mrl into my browser it plays fine. I wondered if it requires a login I'd forgotten about or something, but the link still works in a private browser in Chrome. If I download an episode manually and drop the file into VLC, it plays fine.

I tried to check the log mentioned in the error, but couldn't find it.

Looks like https://pdcn.co/e/http://feeds.soundclo ... -leong.mp3
redirects to https://cf-media.sndcdn.com/Ao5ruZbQ50F ... MXM5DG6EPQ

which might be the reason why it doesn't work.

Also notice the https://pdcn.co/e/http://feeds.soundcloud.com and pdcn.co returns this error message:

Code: Select all

Corrupted Content Error The site at https://pdcn.co/ has experienced a network protocol violation that cannot be repaired. The page you are trying to view cannot be shown because an error in the data transmission was detected.

The location redirects to an invalid address. Server side issue.
