Receive error when adding feeds

I am getting the same thing when viewing a previously active feed. Using RSS_MI version 3.13 on WP version 4.1. Had same issue on 4.0x before I upgraded.

Also see this when running diagnostics ( …/diagnostics.php on line 35)

Somewhere in trying to do a little debugging, I think I saw this particular feed timed out when retrieving it. It could be that my hosted server is blocking this feed, but it would be nice to see a time-out or some other message, rather than a Fatal Error. (however removing the feed from production still does not alleviate the issue on the diagnostics page)
