Can't deploy from home

Hey there,

I can deploy my app from the office with no issues. For some reason, I can’t deploy from home due to network issues.

My guess is that has some firewall configuration which blocks me from the deployment. I can’t see where it’s configured though.

Hi Azer, this could be a big directory or file that’s uploading slowly. Try running du -sh in the same directory you are running fly deploy to see approximately how much is getting uploaded to the remote builder.

If you don’t have a .dockerignore file already, try making one and excluding the things that are not needed like build artifacts that will be created in docker build (e.g., _build for elixir, node_modules for nodejs, etc).

@tvdfly thanks for the answer :slight_smile: In a fresh new project, I have the exact same issue and this time there isn’t any big files at all. There is only node_modules and it’s ignored.

To highlight, I can deploy without any issues from office. Weird enough, it only fails at home.

Just in case anyone runs into this. I had this problem because of a network filter (Little Snitch in my case).
