I think we can close this "ticket" as the issue has been resolved with the release of Squeezebox 7.7.6. I didn't try the podcast feeds immediately before installing the update, but I presume it fixed the problem.
From the changelog:
#18151 - some server don't accept port definition in header when it's a default port. #18152, #143 - HTTPS download fails: Connect times out lack of certain headers.
I can finally go to sleep while listening to old Bombcasts again. :)
Two images have been posted by Playdead on various platforms, teasing a new project post Inside. No more information beyond the images as far as I can tell. They look just as dystopian as Playdead's other work. I'm looking forward to hearing more about their new project. Limbo was truly a masterpiece and Inside had its moments, at least in my opinion.
