When attempting to connect to my own server, I get "Unable to Authenticate. Authentication servers are down. Please try again later." I have checked the help.mojang.com page for the server statuses, and they all show that the servers are up. I have tried repeatedly today, as well as trying 1.7.5, 1.7.9, and 1.7.10 versions of both server and client. (I can login to MC just fine, though, and nothing in the network has changed since I last successfully logged into my server)

Below is an excerpt from my log, showing my attempted connection from another computer on my network. I get the same response (with a different IP) when trying to connect from the same computer as the server.
