git - git unable to open connection

Question

ssh cant connect to GitHub, but git clone occurs unable to open connection. How can I resolve it? when I use puttygen generate PPK, I can git clone code by tortoisegit.

git version 2.24.1.windows.2 TortoiseGit 2.9.0.0 (C:\Program Files\TortoiseGit\bin)

$ ssh -vvvT git@github
