flyctl deploy: You hit a Fly API error with request ID...

Just signed up for fly and went through the sample Python/Flask app. Tested the app locally and all seemed good. Then ran the following commands:

> flyctl auth login
> flyctl launch
> flyctl deploy

After the image was built, pushed to fly and a release created, I got a not-so-helpful error message “Error You hit a Fly API error with request ID:…”

Any ideas on how to resolve? Thanks!


Same problem here a few minutes ago. I put together a custom dockerfile, but it exposes port 8080, I can run the docker image and hit the server it runs from a browser on the host machine. fly launch worked, but fly deploy reports the same error as above, with a different request ID.

Same with hello fly from the getting started section from docs

same here, Error You hit a Fly API error with request ID
this is the toml file looks like

app = “appname”
kill_signal = “SIGINT”
kill_timeout = 5
processes =

i think its with server issue

Same here. Getting the same exact error since few hours ago

Same situation. I even tried switching regions with no success.

Same issue. Can’t success with flyio/hellofly:latest or other Docker Hub pre-built images.

Same issue here,

Edit: Resolved by doing flyctl launch

Recreate everything and run flyctl launch works

FYI the issue seems resolved - I just ran fly deploy and it deployed without error. Didn’t need to rerun fly launch.

I reran fly launch and it seemed to get further, then crapped out with a separate python error:

Not sure why, I’m simply deploying the cloned fly Python sample app.

Then tried flyctl deploy and got:

Hi! I had a same problem after re-creating my app builder.
I removed my app then tried flyctl launch but it doesn’t solve my problem.
Also I tried repeating flyctl deploy , the error message remains.


We’re working through an incident at the moment:

That’s likely related - give it a try after the issue is resolved and let us know what you see then!

Heya, in case you missed it, this should be resolved now


Hi! I an new to and just run the python tutorial in the document.
However, the problem as above seems not revolved.
Any advice is appreciated.

Maybe your problem will be similar to this:
[URGENT] Contact Lost with instance - Questions / Help -

@Cadulogy Thanks for your advice.
I take a look in this reply and check the
flyctl logs -a MY_FLY-builder
It shows “Deadline reached without docker build”

I think the problem is like the reply as ‘LuxuryMode’
since my deploy error also shows

I am still having this same issue. I managed to deploy the app once by spamming flyctl launch and flyctl deploy until it finally succeeded.

After that I unfortunately accidentally removed the project and now I have been spamming those commands over 10 times and I am still unable to deploy the project…

Oh wait, just now it finally succeeded again. Only thing that I did differently was to open my project in the dashboard and open the monitoring tab while deploying.


flyctl version update
flyctl agent restart


fly deploy

Since 2-3 hours, I am seeing the same error in FRA & AMS (have not tried other regions yet):

image size: 221 MB
==> Creating release
Error You hit a Fly API error with request ID: 01GFNFZ6HN3Z750PDVRA5MEJTD-fra

flyctl upgrade, agent restart, launch/deploy did not help. Neither fly deploy --verbose, nor log provides any additional info.
