javax.net.ssl.SSLHandshakeException when trying to clone GIT on MAC

Question

When trying to clone a VSTS project repo to my Mac (via VS Code Terminal) I get the following certificate error

git clone https://abc-masked.visualstudio.com/Test/_git/Test.UI

Cloning into 'Test.UI'...

fatal: credential helper '!java -Ddebug=true -Djava.net.useSystemProxies=true -jar /usr/local/Cellar/git-credential-manager/2.0.4/libexec/git-credential-manager-2.0.4.jar' told us to quit

I have tried the following:

1. Updated the Java version

2. I downloaded the certificate from my VSTS domain (abc-masked.visualstudio.com) and added it to the Java keystore but that did not help.

   Also, I have git-credential-manager installed.

I am new to git, Can you please point me in the right direction?

Edit: This URL https://abc-masked.visualstudio.com/ when I open in the browser immediately redirects to https://dev.azure.com/abc-masked .So I added both *.dev.azure.com and *.visualstudio.com certs to both Mac keychain and Java Keystore

Answer 1

Virtually, you have to trust the certificate. Get trusted certificate to clone a repo. You can refer my github url, I am doing exactly the same to clone a repo.
