There is certificate file available on this path: google_appengine\lib\cacerts\cacerts.txt
also I have authenticated using gcloud shell and setup proper project. and in ItelliJ app.yml set same project id.
Can anyone help me to solve this issue.
Thanks,

I got a similar error (on linux) when trying to run the development server after upgrading the GAE SDK from 1.9.49 (which worked fine) to currently latest 1.9.51.
After digging on SO and finding suggestions for renaming/removing the cacerts.txt file equivalent to the one you mentioned I tried it, but it didn't help - some other related error popped up.
So I just copied over the respective cacerts.txt file from the 1.9.49 SDK and things are working fine again.
