“Bad Response From Server” when posting

Hi, I’m trying to unscrew up my blog and feed (right now it doesn’t validate). After re-editing posts for my podcast and trying to re-publish them WP gets hung up then gives me a “Bad Response From Server” message. The posts still show up on the blog but I can’t believe that something isn’t totally messed up.

Should I delete the posts and re-publish them from scratch?

Here’s the blog and the feed:
Blog: dailyfungopodcast.com
Feed: https://www.dailyfungopodcast.com/?feed=rss2

Any help is much appreciated.
