github 无语的问题，Host does not exist

Unable to open connection:

Please make sure you have the correct access rights
and the repository exists.

如果github desktop和git pull 和git clone全部都出问题了，那问题出在路由器，或者dns上了，
在cmd中ping不同，不过是设置cmd代理或者设置git代理都没用，也就是cmdgit clone就提示host无法访问。
后面我又开窍了，我于是想到我直接拿个网卡连主路由器wifi看看
果然可以了，

由于我是旁路由组网，怎么设置网关没有bug还一直没找到办法，主要是打算让旁路由经过一些逻辑然后再转发给我的电脑的，而且不影响主路由，显然现在有点毛病，除非网络隔离，旁路由和主路由不在一个网段，但是显然我不能这么做，我是做工控机器组网，需要公网经过主路由访问到旁路由的ip端口。

github desktop的错误信息
Authentication failed. Some common reasons include:

• You are not logged in to your account: see File > Options.
• You may need to log out and log back in to refresh your token.
• You do not have permission to access this repository.
• The repository is archived on GitHub. Check the repository settings to confirm you are still permitted to push commits.
• If you use SSH authentication, check that your key is added to the ssh-agent and associated with your account.
• If you use SSH authentication, ensure the host key verification passes for your repository hosting service.
• If you used username / password authentication, you might need to use a Personal Access Token instead of your account password. Check the documentation of your repository hosting service.
