What kind of special characters?

As an aside, why are you logging in via the console, anyways, when it's so easy to SSH into your cloud server?

I had the same problem several days ago. Sent a trouble ticket in. DO power cycled the server and all was well again.

You could try to power cycle the server yourself.

VD I myself had to use the console because my ssh is accessible only by my home ip and my isp actually did change my ip. Think I had the same ip for over a year.
