Self-Hosted unable to authenticate API due to CORS

[hasty olive]

Hi team, I hope you are well

I'm fairly new to Directus, but have an ok understanding with website setup.

I have a self-hosted instance using a docker container, I also have nginx and letsencrypt in the docker-compose file to run so that I can access my instance on port :443

I have entered the CORS configuration to my docker-compose Environment variables as per the Directus documentation, but no matter what settings I put it makes no difference to my connection error.

My question is, do I need to make the changes to the nginx config as well? Or should the Directus env settings be correct?

FYI: I'm trying to connect and use data in a Shopify Hydrogen V2 app running on localhost:3000. Is this a potential cause?

If you have to configure the sites in Nginx, open the ports in the firewall and instead of localhost, use 127.0.0.1 and also try 0.0.0.0.0
