Thanks for reporting this error. Could you take a look at Downloads->Log and see which feed had the error?
I think one of the feeds you subscribed to is no longer publishing to the original URL you subscribe to. If that is the case, you should unsubscribe and search for thr podcast and add again (if it still exists)
The problem is that a few other feeds have small issues and i am drowning in “we repaired the issue” messages.
The report was about being able to find the problematic feed by name
