Hi
What is the error that you're getting in response? It seems to be cut off in the screenshot.
I see it's being hosted locally, with a tunnel through ngrok, so you'll need to make sure that your config reflects that.
Firstly, you'll need to make sure that you're running a load balancer that is proxying the `/c/` path to courier. Then you'll also need to make sure that the courier config `COURIER_DOMAIN` is set to the correct value as the HOST header coming in, which is probably the ngrok hostname.
Regards,
Rudi.
