an unknown error occurred (302) when trying to download podcasts - iTunes 12.3.3

Hello,

I recently upgraded to iTunes 12.3.3 and El Capitan, and now I'm experiencing problems downloading podcasts form iTunes.

They show up as downloadable (little cloud with down arrow), but when I click on that I get the exclamation mark left of the podcast, and clicking on that I getthe above error message (302). The link to the podcast works as I verified it in iTunes on another computer.

Reinstalling iTunes does not change anything.

Not all my podcasts experience this issue. I am wondering about perhaps something corrupt in my iTunes files?

Anybody else had this experience?
