Git hangs on pushing to

Question

I'm trying to push my code on GitHub without success. I'm connected to my VPS ( CentOs 8 ) through SSH.

# git push -v
Pushing to https://github.com/xxx/epAPIv2

After 20min, nothing changed. I think something is blocking the connection.

# GIT_CURL_VERBOSE=1 git push

*   Trying 140.82.121.3...

Stucks again. I tried to disable my firewall, make sure I have no proxy, re-install git, every solution I can find on SO, ... no more idea. It used to work on this VPS.

Thanks

One reason is because Git would read the ~/.netrc, which could include an old token.

The other is because the repository is using Git LFS, and as commented here by brian m. carlson

The reason you're seeing this is that Git LFS needs credentials in addition to Git, and there's no way to pass these credentials along from Git to Git LFS.
If you want to avoid this, then you'll need to use a credential helper.
You can run git config --global credential.helper cache to use the cache credential helper which will cache the credentials for about five minutes, or if you're on a Linux system with a desktop environment, you can use the libsecret credential helper if it's available (or, on Debian and Ubuntu, you can copy /usr/share/doc/git/contrib/credential/libsecret/ somewhere else and then build it after installing the libsecret-1-dev package).

You're likely seeing the window because either core.askpass is set somewhere in your config or because GIT_ASKPASS or SSH_ASKPASS is set in the environment. Those are the places we look for an askpass helper.
