Pybytes web authentication flow broken

[leaf]

Tried to login to pybtes, get directed to https://pyauth.pybytes.pycom.io/login which shows error:

Internal error
Uh Oh! Something wrong happened, please try again later, thanks.

Back to login page

Have tried on an incognito window and different computer as well to rule out cookie issues. No luck. Anyone else seeing this? This has been happening for me since last night.
