hi

I installed Mongodb-4.0.9 on the server

And it works well

But with Robo 3t I can not connect and give the following error

network error while attempting to run command 'isMaster' on host

But it's easy to connect with the shell from the server

note: I also tested various versions of Mongodb

thank you

Hi,

I would make sure you are running the latest version of Robo3T (currently 1.3). Version 1.3 is the first to embed the MongoDB 4.0 shell, which would be recommended for better compatibility with a MongoDB 4.0 server.

If the latest Robo3T version doesn't work for you, I'd suggest contacting the Robo3T developers by creating a GitHub issue with details of your application version, deployment type, and the specific error message: https://github.com/Studio3T/robomongo/issues.

Note: there are also more actively maintained admin tools available, such as MongoDB Compass, which have better support for multiple versions of MongoDB server.

Regards,

Stennie

Hi,

Does your server have a firewall configuration that allows direct connection from your IP? If not, it would be expected that you need to use SSH port forwarding or a proxy to connect.

Are you able to connect to your deployment from your local machine using the mongo shell or Compass?
