Error An unknown error occured.During deploy.

Fly will be able to help more than me (like if it’s a host/region/API etc issue at their end), but in the meantime this is my go-to list of things that seem to fix various errors. Can’t hurt to try them while you wait:

  1. Run fly version update to get the latest version of the CLI and try another deploy

  2. Run fly doctor to see if it can diagnose any errors

  3. Try restarting the agent: fly agent stop; fly agent start and try another deploy

  4. Enable CLI websockets (instead of the default UDP): fly wireguard websockets enable and try another deploy

  5. Try removing the latest wireguard peer:

fly wireguard list
fly wireguard reset
fly wireguard remove
... remove the one that was initially listed from the list command
  1. If using a remote builder, try destroying that remote builder in case there’s a random fault/disk full etc) with that one:

fly apps list (to get its random name) then fly destroy builder-name-here. And try another deploy

If none of those help, I’m out of ideas. But hopefully one of them may.
