梯子正常延遲不算嚴重，但在使用git push時反復出現
fatal: unable to access 'https://github.com/irvingwu5/xxxx.git/ Error in the HTTP2 framing layer
Failed to connect to github.com port 443 after 136353 ms: Connection timed out

將git的網絡配置與梯子端口相同

git config --global http.proxy http://127.0.0.1:7890 

git config --global https.proxy http://127.0.0.1:7890
