Today a crawler hung up, and the test found an error: unable to verify the first certificate
Here is an effective solution, reference: https://www.reddit.com/r/node/comments/7vyc2q/cant_get_https_request_with_certificate_to_work/
reference:
strictSSL - if true, requires SSL certificates be valid. Note: to use your own certificate authority, you need to specify an agent that was created with that CA as an option.

Just add a parameter to the request:
strictSSL: false
That's it.
