Hey Hi,
I was also facing this issue and I found a solution.
Please do follow the steps below
1. open cmd in some folder and run git clone <team server git link
>
To Find Team server link refer below image.
2. If you get error fatal: unable to access then do remove .gitconfig file
Remove or rename from "C:\Users\<user account>\.gitconfig" to old.gitconfig
3. [OPTIONAL] If you get SSL error then do follow this step.
Open internet options then clear SSL certificates
To open Internet Options just do search in windows search
from internet Options click on content and clear SSL Certificates by clicking on clear SSL State.
Now the issue will get resolved. Now open Mendix Platform - Apps and edit your app in Mendix Studio Pro. From mendix portal you will get SSL certificate req.
If still you face issue please reinstall the git from
https://git-scm.com/downloads and install it with the administrator credentials. and please check the git path in system environment variables under path.
Thanks,
Dhananjay
