Connection timed out

When I look up the address for git.drupalcode.org, I get:

$ dig git.drupalcode.org

Which does not include what it is resolving to for you, 151.101.246.217. That IP is a Fastly PoP, so it still could be correct, since you are in a different part of the world. I still recommend verifying DNS is resolving properly for you.

Otherwise, to debug your connection, you can run the Git command on its own, prefixed with GIT_CURL_VERBOSE=1, like GIT_CURL_VERBOSE=1 git clone --mirror -- 'https://git.drupalcode.org/project/paragraphs_features.git'
