We don’t have a hosted login page enabled for from around 12 noon GMT (~1 hour) ago we are unable to login to our applications. This has suddenly effected all our Auth0 tenants.

Having same issue for some of our stuff. Normal logins via API are working fine however the problem we’re having is with impersonation, but still 504 error ---

Hmmm … the forum ate my post … lets try this again. We had the same problem and for us updating the Auth0 package solved it. ![alt text][1] Hope the post is not getting eaten again and that it helps. Good luck, Gerald ---

The situation that you’re noticing with impersonation is also caused by the same issue. The engineering team has identified the cause and is now working on a fix ---
