These steps did not work for me.
I got the following after running flyctl deploy --image:
2 desired, 1 placed, 0 healthy, 1 unhealthy [restarts: 2]
→ v3 failed - Failed due to unhealthy allocations - not rolling back to stable job version 3 as current job has same specification and deploying as v4
→ Troubleshooting guide at Troubleshooting your Deployment · Fly Docs
Error abort
