Cannot access SDL Language cloud from within Studio 2017

All of a sudden, right in the middle of a project, I can no longer access language cloud from Studio 2017. Website access still works. I even tried resetting my password but to no avail. Studio won't let me sign in, reporting that my email address or password is not valid.

Closed and relaunched Studio. Cycled off/on my PC. Nothing changes. Any clue?

Thanks
