Started to get error using nodemailer and mandrill smtp.

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

Could you please describe, what can be the reason

It happens hour ago with different servers on different domains/ip to me
maybe problems on Mandrill's side
but I am not sure

Changing mandlill's api key does not help

this was a problem on mandrill side

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.

Apply below in your transporter setting -

tls: {rejectUnauthorized: false},

For Example :

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