Docker Compose:

services:
  newt:
    image: fosrl/newt
    container_name: newt
    restart: unless-stopped
    environment:
      - PANGOLIN_ENDPOINT=https://pangolin.app.example.com
      - NEWT_ID=foobar
      - NEWT_SECRET=foobar

Seems to be coming from here:

Appreciate any support on this!

Hi! Does your actual endpoint follow the proper host format? You can double check what is sent from the server in the server config/config.yml file under gerbil base_endpoint

What do you have as your gerbil base endpoint? Is it ipv6? We might not
support ipv6 in here until RC comes out to GA.
