Started to get error using nodemailer and mandrill smtp. CERT_HAS_EXPIRED Error: certificate has expired

Question

We are using nodemailer and mandrill smtp.

Started today we got this error for few different web services

Error: { [Error: certificate has expired] code: 'CERT_HAS_EXPIRED' }

It happens for localhost and remote servers for different web applications What can be the reason?

this was a problem on mandrill side

UPDATE

Expired Certificate Errors A roll out of new certificates last week has caused some users to experience problems sending mail—this was due to the expiration of the old certificate and an issue in our configuration. The users effected were sending through SMTP with STARTTLS. HTTPS API calls were not affected. We are currently working on a fix and will update when resolved. 12:21 PM UTC The configuration error was corrected at 12:05 UTC. SMTP with STARTTLS is now working correctly in all regions.

Have you verified that the server SSL certificate is in fact not expired? — Thusithz, Dec 18 '15 at 11:59

I was getting same error. Use below in transport config :

tls: {rejectUnauthorized: false},

For Example :

var transporter = nodemailer.createTransport({
host: 'smtp.example.com',
port: 587,
auth: {
    user: 'username',
    pass: 'userpassword'
},
tls: {rejectUnauthorized: false} });

Add this at the top of your file:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';t

Warning This disables HTTPS / SSL / TLS checking across your entire node.js environment. Please see the solution using an https agent below.

This seems like fixing a symptom instead of the actual cause. – robertklep Dec 18 '15 at 13:51
