> Because tlsAllowInvalidCertificates uses true to signify that verification should be disabled and ssl_verify_certificate uses false to signify that verification should be disabled, the boolean is inverted before being used to set ssl_verify_certificate.

One of the "disabled" should be "enabled".

tlsAllowInvalidHostnames has the same issue.
