option to disable tls verification?

[miconx]

i try to sync from gitlab to gitlab and get the following error: ERR POST https://gitlab.itest.lan/api/v4/projects: 422 {message: HTTP open_ssl/ssl/ssl_error error: SSL_connect returned=1 errno=0 peeraddr=1.2.3.4:443 state=error: certificate verify failed (self signed certificate in certificate chain)}

but from the host i am using the certificate CA ist correctly integrated - a test with openssl s_client -connect ... works fine how can i disable the tls verification?
