I kept getting logged out as well. In fact it took me several tries to log in today even with the correct password. Then I cycled through a bunch of other passwords, had to wait to log in, then used the same one I tried a bunch of times before and then was able to log in. That's the first time that had happened to me, but the logging out even with the keep me logged in option chosen, that had been happening for a while now. Just figured it was on my end some how.
