git push -u origin master错误:收到HTTP代码0

我多次使用此命令，并且每次都有效，但是今天在创建存储库并再次使用它之后，发生了错误:

I used this command several times and it worked every time but today after I created a repo and use it again an error occurred:

git push -u origin master

它给了我这个:

error: Received HTTP code 0 from proxy after CONNECT while accessing https://github.com/[myrepo]

fatal: HTTP request failed

我使用 echo $ http_proxy 并获得了 http://127.0.0.1:48100 .有时是一个用于我的Firefox.)而且我使用了 unset 命令，但它仍然给我同样的错误.有没有一种方法可以将我的代理服务器永久设置为无?

I used echo $http_proxy and got http://127.0.0.1:48100 .But I don't remember I ever set this.(I do use this one for my firefox sometimes.) And I used the unset command but it still gave me the same error. Is there a way I can set this proxy thing to none permanently?

还有其他方法可以实现这一目标吗?

Is there some other ways to achieve this?

感谢您的帮助！
