I'm a Taiwanese student and my english grammarly is not good ,but I can understand what you say. I want to use git to push my file(3GB) to heroku but failed.
I tried.
git config --global http.postBuffer 800000000.
git config --add remote.heroku.proxy "".
git config --global http.proxy ''<<
When I git push heroku master and then it showed fatal:
unable to access 'https://git.heroku.com/pushboss.git/': Could not resolve proxy: ''.
so I have to type git config --global --unset http.proxy.
this is my error message:
error: RPC failed; HTTP 504 curl 22 The requested URL returned error: 504 GATEWAY_TIMEOUT.
fatal: The remote end hung up unexpectedly.
Heroku's file system has a 500MB limit for your app and its components. Whilst it is possible to store static files within that, you are encouraged to use third party storage (such as AWS S3 / Azure Blobs etc) for anything other than code, such as images, video, and other media.
I would guess that your git errors are due to the 3GB file far exceeding the 500MB limit Heroku has for the whole app!
