It all depends on what you're experiencing.
You could try using Firefox and seeing if the problem persists o you could try logging in to your mobile device and seeing if that helps. Sometimes you might have to wait it out if it's that annoying, no proxies error message..
But if it's that error message whenever you login then you can check the post that Red made regarding this.

Adding my own two cents in. IN case you have problems with the login page staying logged in, try using a tab refresher such as refreshthis.com or urlreload.com and set it to refresh every 25 seconds. This may not be part of the problem you are experiencing currently, but it may help in future. :)
