Error: Unable to reach host: "api.twilio.com"

I'm using node-twilio and I keep getting a "Error: Unable to reach host: "api.twilio.com" for every request. We've checked the packets via mtr and they are reaching api.twilio.com. Running on debian on GCE.

It may be because of your internet connection.

After couple of minutes, if you have internet, try again and it should work.

After days of digging around, found out that the node-twilio module shows many errors incorrectly as:

"Error: Unable to reach host: "api.twilio.com".

The following lines:

var error = null;
if (err || (response && (response.statusCode < 200 || response.statusCode > 206))) {
    error = {};
    // response is null if server is unreachable
    if (response) {
        error.status = response.statusCode;
        error.message = data ? data.message : 'Unable to complete HTTP request';
        error.code = data && data.code;
        error.moreInfo = data && data.more_info;
    } else {
        error.status = err.code;
        error.message = 'Unable to reach host: "'+client.host+'"';
    }
}

This happens because you have a self signed certificate in your chain and the underlying module twilio depends on is request, which is throwing the following error: Error: SELF_SIGNED_CERT_IN_CHAIN but this is not the error being thrown by node-twilio (bad error propagation on their part)

There are 2 fixes:

1.Tell nodejs to ignore self signed certificates in chain by setting:

export NODE_TLS_REJECT_UNAUTHORIZED=0

  1. Find the self signed certificate and remove it from the chain. Here is an example using openssl: https://serverfault.com/questions/590870/how-to-view-all-ssl-certificates-in-a-bundle
