I have this flow

when I try to deploy my flows I get this message Error: More than 1 database name in URL  
here is my url : mongodb+srv://username:password1234@cluster0.hx0l5.mongodb.net/capteurs?retryWrites=true&w=majority

Might be due to specifying the database name "capteurs" in the host field and in the database field?

Try setting the connection host to the host name / cluster DNS name only (i.e. remove `/capteurs`) as suggested in the [readme](https://flows.nodered.org/node/node-red-node-mongodb)

@sabayke

You currently have a full url in the Host field - including `<username>:<password>` and other details.

Have you tried with just the Host name in that field - `cluster0.hx0l5.mongodb.net` ?

Ah right - you're trying to use the srv record... I assume the node doesn't know how to work with those.

If I remember rightly, the hosted mongodb service can also provide you the 'normal' hostname/IP to use, rather than the +srv connection string.

Another possible reason .. although i havent worked with cloud based mongo dbs .. could be that Atlas server requires a step to whitelist an IP from where you want to access the cluster.

**[Add Your Connection IP Address to IP Access List](https://docs.atlas.mongodb.com/security/add-ip-address-to-list)**

@sabayke Have you done this step ?

With the [Compass](https://www.mongodb.com/try/download/compass) tool.. can you connect to your cloud db ?

Also .. what mongodb node / version are you using ?  
That configuration screenshot doesnt look like its the **[node-red-node-mongodb 0.2.4](https://flows.nodered.org/node/node-red-node-mongodb)**

Can you try the above node instead that is more often updated and its config has options closer to your needs

</div>

you have to be in the `c:\Users\owner\.node-red` folder to run that command  
and make sure node red is not running

but why dont you uninstall it from the Palette that is easier ?  
first you have to delete any instances of the mongo nodes in your flows and also any Configuration nodes related to it

You are using again the whole string .. use only the server `cluster0.hx0l5.mongodb.net` in HOST
