Robo 3T Error : Network is unreachable

Question

I am trying to connect Robo 3T to my online database and it doesn't seem to be working. I am able to connect to local database with it. I tried connecting using MongoDB Compass and the Details and Auth are working fine and I am able to connect. But when I connect with the same details in Robo 3T, it doesn't seem to be working. How do I fix this? I am using Robo 3T Version 1.1 I tried same with Robomongo 1.0, and still getting the same error

Answer 1

For me, reinstall mongodb and restart my computer worked fine.

Answer 2

Go to services.msc and then search for mongodb server and then run the server in running status. I have solved my error in this way.

Answer 3

You may be seeing the following issue when starting the Robo 3T Application:

Just follow these steps, and you are good to go:

1. I'm using MacOS, so in your terminal use the following command to start your MonogDB Server: /Users/vanthoff/mongodb/bin/mongod --dbpath=/Users/vanthoff/mongodb-data

mongodb-data: Directory you must have created to store all your Data.

2. After starting the server, go to RoboT 3T Application and connect to the server. It will start working. You can also Test it by double clicking you MongoDB Server name. It will look something like this when it starts working:

I hope it's going to work for you too. Amigos..!! 🙂

Answer 4

Go Inside bin folder of MongoDB and run mongod command:- C:\Program Files\MongoDB\Server\4.2\bin then open command prompt at this location and run mongod command & then try to connect with Robo 3T . It works for me.

Also create data folder inside your C: drive & then create a db named folder inside data folder. that's it.

Answer 5

This might help, my robo mongo server is hosted in cloud. I have setup the mongodb but could not connect to it using Robo3T. Keeps telling network timedout (this means network problem). Been reading a lot to figure out the cause, suddenly I remembered I have also a security group in my cloud network. Just include the mongod port 27017 in the list of allowed incoming. That's it!

Answer 6

sorry if i'm late to this but i was running through the same issue all morning. You have to go through a few things first so you can troubleshoot easily

1. Restart the database from the terminal, hitting the database at the correct path and let it run in the background.
2. if the database is running then go through checking the local host address, and replace it with 127.0.0.1 instead of the generic localhost:27017

Answer 7

I had this symptom, and the ultimate fix is not yet captured in an answer here.

I was trying to connect to a mongo instance in the cloud using Robo 3T, and I was getting the "Network is unreachable" message.

Oddly, I could connect from using Robo 3T inside a Parallels VM on the same machine.

This led me to try the full Studio 3T on my mac, which could also connect just fine.

Ultimately, I discovered that there was an old dotfile from an ancient version of Robomongo that was causing the problem. rm -rf .config/robomongo did the trick. Now I can connect with the ordinary, free Robo 3T.

I'm guessing that I had an expired trial of Robomongo, from back before it was free, perhaps?

Answer 8

I also meet this problem when I use Robo 3T on Mac. I think there are some things you need to check to help you know what's the problem.

First try to ping the mongo server in your terminal to see whether you can get responses. If so, that's means you may set wrong mongo config in you Robo 3T.

If you cannot get the response, that means there is something wrong with your network. You should check your DNS and your network gateway. For example my DNS is 172.16.* and my network gateway (execute ifconig and check en0) is 172.17.*. And they are not belong to the same network segment. (Actually, even if they are on the same network segment, things won't work if someone polluted your DNS server.)

That's the problem. The DNS that you are using cannot interpret your mongo host correctly. Someone may had polluted this DNS server.

You can have a try on ping xxx(your mongo-server) @8.8.8.8, which will use 8.8.8.8 as your DNS. If everything goes well, then you get the sollution.

Sollution: Manually set DNS for your devices. For example, Google's public DNS, 8.8.8.8 and 8.8.4.4.

Actually, if you run dig xxx(your mongo-server) before and after you manually set DNS, you may find the response Ip differently.

Answer 9

Start the MongoDB service from the task manager. Worked for me.

In my case both mongod and mongo.exe was throwing a 100 error code.

Answer 10

As said above, this is probably due to BindIp, if you use mac and brew to install it you won't find anything in /etc/mongod.conf instead you find it in /usr/local/etc/mongod.conf

systemLog:
  destination: file
  path: /usr/local/var/log/mongodb/mongo.log
  logAppend: true
storage:
  dbPath: /usr/local/var/mongodb
net:
  bindIp: 127.0.0.1

Change BindIp with caution!

And same goes for running it, to start MongoDB manualy use:

mongod --config /usr/local/etc/mongod.conf

or configure autostart on login with launchd by typing:

brew services start mongodb

I've also encountered corrupted data files on my local computer here:

/usr/local/var/mongodb

just removed them and it worked, you could see in the log that errors like:

Answer 11

Just change your bind_ip in /etc/mongod.conf from 127.0.0.1 to 0.0.0.0 then restart the service, and it works for me~

Answer 12

Start your command prompt on windows.Go to the bin folder of Mongodb through command prompt and type mongod and enter.Now try to access again

Answer 13

This means mongo server is not started. You need to run mongod command on the terminal to start the server.

if you do not have mongo db installed on your machine. Download and install from the Link.

Answer 14

If you get the following error then you should also check the following:

The atlas servers at least require this setting, if you do not choose it, then you generally get the Network is unreachable message.

Also if you are using Atlas then you should check the Authentication tab and select SCRAM-SHA-1, however this generally results in an authentication error not a network unreachable one.

Answer 15

A better solution is to comment out or remove the bindIp setting from the config file /etc/mongod.conf

You must restart the service for the change to take effect
