(mix phx.gen.release --docker) (RuntimeError) couldn't fetch https://hub.docker.com/v2/namespaces/hexpm/repositories/elixir/tags?name=1.15.7-erlang-26.0.2-debian-bullseye-

Help please! I’m running fly launch but getting stuck at the mix phx.gen.release --docker stage. The error code is (RuntimeError) couldn't fetch https://hub.docker.com/v2/namespaces/hexpm/repositories/elixir/tags?name=1.15.7-erlang-26.0.2-debian-bullseye-

I got a feeling it’s my VPN issue since i’m in China. For example I’m unable to run curl -I https://docker.com/ on my vscode cli console. However, I can access docker no problem with my browser.

I have 2 options.
Option 1: Dont use fly launch
I can run the mix phx.gen.release then manually write the docker file. Problem is all the tutorials I see requires me to run fly launch regardless. This means it still gets stuck at the docker stage. Is there another option other than fly launch?

Option 2: Make sure I can call docker.com from my vscode cli
I suspect the call is failing because of my VPN issue. If I can fix this, I can just run the standard fly launch and this would be no problem. Except I’m super confused on how to do this with vscode. What I do know is my VPN listens on a http proxy 59527

My versions:

Erlang/OTP 26
Elixir 1.15.7
{:phoenix, "~> 1.7.2"}

Edit: I tried using iterm to curl. I can access docker.com but not hub.docker.com. The i still face the same problems as mentioned above

Solved on my other thread which I posted on fly.io’s forum page.
