Error: SSL: CERTIFICATE_VERIFY_FAILED about serenata-toolbox HOT 2 CLOSED

Hi @WalnerPessoa, I edited your post just to include the error message, translate one or other sentence and included the error message in the title. This way if others run into this same issue, it would be easier for them to find this issue, and they have all the information available here, ok?

Anyway, from your post I understand you're using macOS's Python 3.6, which happens to have no SSL certificate at all. This StackOverflow answer might help you get around this issue, but I do recommend using pyenv to handle Python installations in macOS and Linux systems:

This isn't a solution to your specific problem, but I'm putting it here because this thread is the top Google result for "SSL: CERTIFICATE_VERIFY_FAILED", and it lead me on a wild goose chase.

If you have installed Python 3.6 on OSX and are getting the "SSL: CERTIFICATE_VERIFY_FAILED" error when trying to connect to an https:// site, it's probably because Python 3.6 on OSX has no certificates at all, and can't validate any SSL connections. This is a change for 3.6 on OSX, and requires a post-install step, which installs the certifi package of certificates. This is documented in the ReadMe, which you should find at /Applications/Python\ 3.6/ReadMe.rtf

The ReadMe will have you run this post-install script, which just installs certifi: /Applications/Python\ 3.6/Install\ Certificates.command
