Hello Fly Community I use fly.io to deploy a NodeJS app. The app uses 2 performance-2x machines. I find it that the fly deploy command is not working as it should most of the time. When invoking the command only one machine seems to get updated while the execution gets stuck in the terminal on the first machine. Below are 2 images to better explain the problem.
The execution of the fly deploy command gets halted and stuck in the terminal. Never getting to the second machine.
The Fly Dashboard is successful at showing that the first machine was re-deployed, but nothing is happening to the second machine and it seems that the re-deploy status did not reach you guys because the terminal is stuck.
I see a similar problem; it hangs waiting for an instance to become healthy and eventually the process times out:
Run flyctl deploy --config fly.prod.toml --image registry.fly.io/prereview:752001716461960d10a933f3deb2d1cc14f15eff

However, I can see in the dashboard that it became healthy, leaving multiple versions running (in this case, the first two instances updated successfully, but the remaining two hadn’t).
In my case I usually first restart both machines and then do the re-deploy again. However again only 1 machine (usually the one which was not deployed on the first try) gets deployed, leaving the other stuck again. This makes it so that the machines are actually not on the same deploy version

sometimes the deploys work as expected, but most of the times they get stuck in this state…
