I want to push my commits to a Bitbucket repository but this error occurred:
Fatal: unable to access \'https://myUsername@bitbucket.org/myUsername/myReposito
The corporate HTTP proxy behind which I currently am sporadically gives this error. I can fix it by simply visiting bitbucket.org in a browser, then retyring the command. Have no idea why this works, but it does fix it for me (at least temporarily).
