When trying to install the C/C++ extension, Visual Studio Code gives me the error:
Error unable to verify the first certificate
What should i do?
What OS are you on? Does this repro for other extensions? What does it say in the Output window?

I guess this issue will help.

TL;DR - try setting "http.proxyStrictSSL": false in your settings.json
