We are using absinthe for websockets connections, it’s working fine in dev, but in our stage environment we get the following error: WebSocket connection to ‘wss://outsite.com/websocket/websocket?vsn=1.0.0’ failed.
To make it work on dev I had to change:
config :site, SiteWeb.Endpoint,
check_origin: false,
Now on stage, after that change, the error appears. This is the full config of stage:
use Mix.Config
api_url = System.get_env("API_URL") || raise "Missing API_URL."
config :site,
canonical_host: api_url
config :site, SiteWeb.Endpoint,

What could I be doing wrong?
