Changes in proxy from 2.1.1 to 2.2.2

Using nginx as my proxy. With jupyterhub I am using GitHub - cwaldbieser/jhub_remote_user_authenticator: REMOTE_USER authenticator for Jupyterhub.

In 2.1.1 I am able to properly authenticate and go about my business.
However in 2.2.2 (same configuration as 2.1.1) I keep getting

Redirect loop detected on /hub/user//lab/workspace/auto-7?redirects=2

And it asks me for a username and password.

Is there a way to mitagate this?

Hi! Can you turn on debug logging and show us your logs?
