First app fails to deploy

Hi all,
Today I launched my first app, but I encountered some problems.
Could anyone help me check what is the problem here?

The following is the output (by changing some personal info):

$ flyctl launch --name myappname
Creating app in /home/myname/myappname
Scanning source code
Detected a Go app
Using the following build configuration:
Builder: paketobuildpacks/builder:base
Buildpacks: gcr.io/paketo-buildpacks/go
Automatically selected personal organization: Tapir Liu
? Select region: sin (Singapore)
Created app myappname in organization personal
Wrote config file fly.toml
Your app is ready. Deploy with `flyctl deploy`
? Would you like to deploy now? Yes
Deploying myappname

$ flyctl deploy
Deploying myappname
==> Validating app configuration
--> Validating app configuration done

TCP 80/443 ⇢ 8080

Error An unknown error occured.

$ flyctl logs

(hang here ...)

BTW, there will always an app with a random name appears in my app list.
It is surely not created by me. Why?

@tapir.liu It looks like it timed out while creating your remote builder. It’ll usually work if you try again.

The app you’re seeing is the remote builder. It turns on as needed then stops when idle. You can remove it if you want and it’ll get created if you need it again.

Thanks for your help.

I have tried it several times, none work.
It would be helpful if the error message is more specific.

Do I need to setup a wireguard proxy?
Or does flyctl support sock5 proxies?
And will github action help here?

I have the same issue. I had tried the ruby getting started and the go getting started.

Example in WSL2:
