Hello! 

The connection string with “mongodb+srv:” is the for the new version of MongoDB Atlas and this stage only works with old version of MongoDB. To connect it you must tu use a “mongodb:” prefix. But, If you need to use a origin stage MongoDB Atlas with Opblog, please open a feature request and we will plan it for a future release.

Thank you!

can please provide configuration of  the full connection string of new version.....

Hello!

The use of mongodb+srv: connection string modifier automatically sets the tls option to true for the connection. You can try changing the prefix to mongodb: and managing the tls if necessary. Hope this works.

Thank you!
