向github push代码报错如下：
fatal: unable to access 'https://github.com/projectXX.git': OpenSSL SSL_read: Connection was reset, errno 10054
解决办法：检查本地账户和github账户是否一致，如果不一致，要切换本地账户。详细步骤参考：Git如何切换账户
再次push代码，又报错：
Push failed Unable to access 'https://github.com/projectXX.git/': Failed to connect to github.com port 443 after 21066 ms: Timed out
连接超时了，解决办法：先弄清楚自己VPN的ip和端口号。然后给Git设置代理。具体操作步骤参考：Failed to connect to github.com port 443: Timed out
再次push代码，又报错了：
