Why do my ubuntu server parsing The certificate of github does not correspond to the github website? [closed]

When I try

git clone https://github.com/xixi-cathy/regX.git

It returns an error shows "fatal: SSL: certificate subject name (*.inkafactura.com) does not match target host name 'github.com'".I investigated whether an external proxy was being used(like "echo $https_proxy"), but the results obtained still cannot rule out the possibility that no external proxy was employed.Belows are my curl and openssl output:
