[git] Git: Could not resolve host github.com error while cloning remote repository in git

I've had the same issue after running out of disk space. Closing and reopening terminal fixed it one time. Restarting my Mac the next.

Some easy things to try before jumping to random commands:

  • restart terminal tab
  • restart terminal app
  • If disk is full (or close to it) free up some disk space then restart terminal app
  • restart machine/OS
