Sonarr's working, but won't connect to localhost (Ubuntu)

I’ve run into a problem. While Sonarr still seems to be working (i.e. my shows are still being tracked and passed along to NZBGet), I can’t connect to localhost to make any changes. I’m using chrome, and I just get the spinning grey line on the tab as it continues to try and load.

I’m running Ubuntu 14.04. The problem started about three days ago. Here’s my log, and the config.xml

log: http://pastebin.com/gdn7Tfqy

Any thoughts?

Nothing in the logs stands out (beyond the OZ failing due to your API limit being reached).

Have you tried restarting the application? The logs on startup should show that its listening on 8989 and if there are any startup errors.

Do you have other apps on localhost to compare with to see if they are working? For example Sabnzbd?

Have you tried going to the local IP address? How about 0.0.0.0? http instead of https?

I probably have no business answering this. But these are instances I’ve encountered in the past.
