Podcast - Episode Unavailable

Starting in July 2024, I can no longer download the 'Retirement and IRA Show' podcast. Up until July, I could download them with no issue. I can still download other podcasts... I am using an older Iphone 6 (IOS 12.5.7) that no longer gets IOS updates, but I can still download other podcasts. I only use this phone for podcasts so I didn't think no longer getting IOS updates was a big deal.

Anyone have any idea what my be causing this?

Thanks you!
