ERROR: SSL verification error at depth 2: unable to get local issuer certificate (20)

[sknilose]

I'm having a problem or would like to suggest a feature.

I was getting ERROR: SSL verification error at depth 2: unable to get local issuer certificate (20) while installing rails. Tried instructions provided here but didn't help:
https://bundler.io/v1.16/guides/rubygems_tls_ssl_troubleshooting_guide.html#what-are-these-certificates

Later I came to know that some security systems (like ZScaler) are also causing this so turning those off helped.

May be we can add this to the guide for the folks who are having similar challenge.

This issue is related to:

• [ X] Network problems
• [ X] Installing a library
• Publishing a library
• The command line gem
• Other

Here are my current environment details:

$ gem env version
3.2.5

I will abide by the code of conduct.

bundler-site repo https://github.com/rubygems/bundler-site would be a more appropriate place for this issue. You are also welcome to update the doc and send PR to the repo directly.
