Unable to pull/push in git repository

When using https you will need to supply password or using a certificate.In your case looks like the certificate is not a valid one.

Try fixing it like this by telling git where to find the certificate:

// Add the certificate to your configuration filegit config --system http.sslcainfo "C:\Program Files (x86)\git\bin\curl-ca-bundle.crt"

Alternatively, you could disable SSL checks:

// or switch off SSL checks completely by executing:git config --system http.sslverify false

Set this in your config to disable it only for the given url and not for all requests

[http "https://weak.example.com"]    sslVerify = false

http.sslVerify

Whether to verify the SSL certificate when fetching or pushing over HTTPS.

http.sslCAInfo

File containing the certificates to verify the peer with when fetching or pushing over HTTPS

I once had the same problem. My problem occured after re-installing git for windows. I'm using git for windows 64-bit on windows 10.

I found out that the installer did not install git anymore in C:/Users/[USER_NAME]/AppData/Local/Programs/Git. Instead it installed it underC:\Program Files\Git.

Nevertheless the old config file C:\ProgramData\Git\config was not edited by the installer. This file still contains the old path so I edited it manually.

E.g. on my system I used

[http]     sslCAInfo = C:/Programme/Git/mingw64/ssl/certs/ca-bundle.crt

maybe you will have to use Program Files instead

     sslCAInfo = C:/Program Files/Git/mingw64/ssl/certs/ca-bundle.crt

EDIT

Like DS said in his comment

C:\ProgramData\Git\config needs to be edited as Administrator.

E.g. right click on notepad and select "Run as Administrator" then open the file.

I was also facing this problem in windows and running git using gitbash. I just reinstalled gitbash, And gitbash automatically managed git certificate and its path needed.
