1 Replace the git link of xserver > url: https://gitlab.freedesktop.org/xorg/xserver.git
2 Replace the git link of xwayland > url: https://gitlab.freedesktop.org/wayland/wayland.git

But still getting unable to access the GitHub.

Thank you for your help.

Hello,

you can set git configuration as below:

git config --global http.sslverify false
git config --global https.sslverify false

then manually test it:
git clone https://github.com/nxp-qoriq/atf.git/

It works on my side.
