Would you mind trying to deploy with the flag --remote-only and see what happens? If that doesn’t work, do you mind going to the monitoring section of the application and providing us with what’s going on?
Could you run fly doctor and provide the output? Also was there a fly.toml file and Dockerfile that was created when you ran fly launch? If so would you mind sharing those as well, to provide more context on the situation?
Can you be more specific about the issue you’re talking about? That’s a thread from a year ago about someone seeing API errors when doing deploys. If you’re seeing the same thing, it’s very unlikely that it has the same underlying cause.
