I have Jenkins setup in Windows Server machine and the job will trigger the build at specified time. Sometimes the job fails with the below exception and when I manually trigger it again it will work fine. I read somewhere that moving id_rsa.* file to GIT installation folder will fix the issue, but it didn't improve in my case. It would be great if there is a way to fix this issue.
