I am using mongo db node inorder to connect to my mongodb database which is installed on my pc,but i am getting this error [image] [image] [image]

Are you using the standard mongodb node or a contrib one? please provide the complete name Does the user/password defined in the node have authority to access the database? Is NR running on the same machine as the database?

[image] I am using standard mqtt node and while installing mongo db i have selected typical installation (default) one.Yes Node Red and mongodb are running on the same machine.the 2nd image is taken from google for just refrence purposes. [image] [flows.json|attachment](upload://uwRBC43vaqp1Z2hO…

[image] I am also not using mongodb node in my current flow but it is showing cannot delete thee old one. [image] [image]

You have to remove the existing mongoldb nodes from your flows and do a deploy. Next use the palette manager to remove node-red-mongodb. Do a deploy and click th link to remove the configuration for the node and deploy again Once that is done you should be able to install node-red-node-mongodb.

[image] deployed done but then also it shows node in use

I updated my last post and you might have missed it. You need to remove the configuration nodes it setup. In the sidebar, click on the 'configuration' icon (see image) and then delete any nodes that show with dashes around them (see image) then deploy again [Screen Shot 2020-10-28 at 4.41.27 AM]

Thanks done ,now which properties we need to set inorder for new node to properly communicate with mongodb database? can we set username and password as blank.? Suppose i made a database using mongodb compass dbname-test and inside it there is a collection/table name-uc11 [image]

Not having used Mongodb, I can't help you with that part. But if it is like other databases, you need a user/password to access it. I would try using a user/password you have setup to access the database.

[image] yes connected but not able to see data in mongodb compass [image] [image] [image]
