Connection to server with self signed certificate

[uranik777]

I get "Error: self signed certificate" errors when connecting to the server by ip address
Error: self signed certificate
at TLSSocket.onConnectSecure (_tls_wrap.js:1317:34)
at TLSSocket.emit (events.js:209:13)
at TLSSocket._finishInit (_tls_wrap.js:792:8)
at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:606:12) {
code: 'DEPTH_ZERO_SELF_SIGNED_CERT'
}
Is it possible to allow such connections (to server without domain name with custom certificate)?
