Can not connect to Atlas Replica set in v4.7 +

Works fine in 4.6, broken in 4.7 as well as 5.0 which means i'm stuck running 4.6 on a mounted .dmg because there is not way to prevent the auto update for constantly breaking my query editor.

Please backup and delete your user data and try it again.

1. Open NoSQLBooster, click Menu-> Help-> Open User Data Directory

2. Close NoSQLBooster

3. Backup and Remove User Data Directory. <NoSQLBooster for MongoDB>\*.*

4. Re-run NoSQLBooster


Issue remains following the above directions on Version 5.0.0

nosqlbooster version: 5.0.0 Enterprise

Mongos version: 4.0.4 Atlas Replica Set

I've tried connecting with every applicable role with the default database set.


Thank you for your feedback. I still can't recall the issue, I can only try to fix the problem by guessing the error code.

We have worked out a test build to try to resolve the issue, please download and give it a try.



That build is at least a step in the right direction. I can connect ( have to use the Atlas Admin Account ) and run basic queries though as you can imagine, using the service level admin account is less than optimal.

Would it be helpful if I supplied a small Atlas database and a set of users with various roles to aid in troubleshooting these issues?


Thanks, please send the accessible MongoURI and test credentials to
