RSS functionality trouble

[m1thr0s]

Hi I am the web admin for the following site and am logged into the owner's account because of the license required. I don't work with RSS at all so I have no idea what I'm doing right or wrong for sure.

site: forums.abrahadabra.com

I'm trying to get RSS feeds working for the site, with podcast support, and I've made sure that the threads are viewable by guests. I am have a problem with it. When I activated it in the control panel under Settings--->Options--->External Data Provider I set it up with settings reading all YES and the default numbers in the fields.

I noted this caused little orange rss feed links to pop up next to the public forum links. When I try to plug in forums.abrahadabra.com to my feed reader, it says it's having trouble connecting to the site. (Feedly for Android)

When I click on those little orange RSS feed buttons they spit back the following information:

I also tried to create a feed under admin panel RSS feeds--->Add New RSS feed. It won't take any sort of URL I could find suggested to me and keeps saying invalid URL

Yours truly,
