Hello,
given that I ran out of alternatives on how to fix this issue, I thought it would be valuable to raise the topic here.
I simply can’t reach a simple Node hello world express app either through HTTP or HTTPS.
Deployment and release are successful. The health check is also green.

- I’ve checked different base image (slim) to see if it was a problem with alpine but no luck;
- I’ve carefully checked if port 8080 is being exposed correctly;
- I’ve explicitly used 0.0.0.0 as host but no luck;
- I’ve tried to remove HTTPS and make it HTTP-only but no luck;
- I’ve tried to follow the troubleshoot article from docs but no luck;
- I’ve tried to see if there was any substantial difference between my code and the Hellonode example that fly.io uses but I didn’t find anything;
I’m out of options =D Perhaps you guys see anything that I’m not seeing?
