Can't login with OpenId

[tsee]

I can't login with my openid via "http://steffen-mueller.net". It used to work. Now, I get this message from blogs.perl.org:

"An error occurred: The sign-in attempt was not successful; please try again."

Am I doing it wrong?

Note: I can't login via MovableType either. If I reset my password, I'll get the email, and set a new password. That brings me to the front page with my name in the top bar saying I'm signed in. When I click 'post', I get to a sign-in screen that doesn't let me sign in with my new password. I'm essentially locked out of the site. Please help.

What has happened with this since 2010?
