Why can't I chat anymore?

I have been using Zendesk support for years and have used chat/messaging for numerous issues. I just tried to chat to report and issue and I get the following message. I am and always have been an admin. Anyone know why I am unable to reach out to Zendesk Support? I know that requests like this don't really belong in the community forums, but without access to support I don't know how else I am supposed to get help!
