querySrv ECONNREFUSED

MongoDB Atlas

Hi @A.T_Rayan,

Error: querySrv ECONNREFUSED _mongodb._tcp.xxxcluster.v1ulb.mongodb.net
at QueryReqWrap.onresolve [as oncomplete] (dns.js:203:19) {
errno: undefined,
code: ‘ECONNREFUSED’,

The error indicates a possible SRV lookup failure.

Could you try using the connection string from the connection modal that specifies all 3 hostnames instead of the SRV record? To get this, please head to the Atlas UI within the Clusters section and follow the below steps:

  1. Click Connect on the cluster you wish to connect to
  2. Select Connect your application
  3. Choose Node.JS for the Driver option
  4. Choose the *Version 2.2.12 or later for the version option
  5. Copy and use the connection string which should begin with the following format:
    mongodb://<username>:<password>....

Replace the original connection string you used with the version 2.2.12 or later node.js connection string copied from the above steps and then restart your application.

If it returns a different error, please send that error here.

In addition to the above, I would recommend also checking out the Atlas Troubleshoot Connection Issues documentation.

Note: although the above workaround may allow you to connect, it may be better to resolve any DNS issues into why the SRV record lookup is failing.

Best Regards,
Jason
