hello,

I have 2 raspberry pi 3 on the same local network, with mongodb + mongoexpress + nodered, installed in the same way on each one.  
the first one is for 192.168.1.1, the second is 192.168.1.2, when I make requests from the first to the second using the node mongodb2 of the kind, mongodb: [//192.168.1.2](https://192.168.1.2): 27017 / db it works perfectly, by cons on the second to the first when I try a request on mongodb: [//192.168.1.1](https://192.168.1.1): 27017 / db, I have a message like: MongoError: failed to connect to server [192.168.1.1:27017] on first connect [MongoError: connect ECONNREFUSED 192.168.1.1:27017].  
I prescribe that the two databases work perfectly.  
I do not understand where the problem comes from.  
have you an idea about this?  
see you  
Nico

Hello, i find a way by myself, the trouble is in the setup of mongodb in 192.168.1.1, you must change in  
etc/mongodb.conf the value bind\_ip change to 0.0.0.0 and also port:27017.  
see you
