无法通过HTTPS克隆私有Github存储库

我在通过HTTPS克隆私有GitHub存储库时遇到问题.如果我尝试使用以下方法克隆我的存储库:

I have problems cloning private GitHub Repositories over HTTPS. If i try to clone my repository using:

git clone https://github.com/{username}/{repository}

我得到了错误:

fatal: remote error: Repository not found

当我尝试在请求中输入我的凭据时，如下所示:

when i try to enter my credentials in the request like this:

git clone https://{username}@github.com/{username}/{repository}

我得到了错误:

fatal: Unable to look up {username}@github.com (port 9418)

克隆ssh可以不使用.克隆公共存储库也可以通过https进行.有人知道我能做什么吗? 我正在使用Windows 10和git for Windows 2.14.13

Cloning over ssh works without. Cloning public repositories also works over https. Does anybody know what i could do? I'm using windows 10 and git for windows version 2.14.13
