Commands not responding

MongoDB University M001: MongoDB Basics
#1

I encounter a problem I can not explain…
I can connect to the cluster (class cluster or personal Atlas cluster) with Mongo shell. I can usually use few commands and then it doesn’t respond anymore. I have to quit and connect again to the cluster.

In the screenshot below, everything is fine until I switch to db video.
Then, the next command doesn’t give anything (neither proper response or error message). So I tried a basic “show dbs”, and it doesn’t work better. I can not even use quit().
So I usually use CTRL+C, which shows the last line (2019-04-11T16:14:45.481+0200 I CONTROL [thread1] shutting down with code:0), to be able to quit and restart.

I have the same problem whatever the cluster I use (class cluster or personnal) and whatever my command (right or wrong)… Sometimes I just disconnect/connect and copy/paste the same command and it works…

Any idea (it’s very annoying to have to connect/disconnect every minutes) ?

Any moderator to help with this problem ?

May be some security settings
Did you try --ssl option along with command you are using

–ssl --authenticationDatabase admin

or some indexes missing on collections?

#4

No, it doesn’t make any difference. I use the “-ssl …” to connect to the class cluster and I still have the same problem.

What do you mean by “indexes missing on collections” ?

#5

I was just suggesting if you are running any resource intensive queries without indexes
May be issue is a different one in your case

Hi @Abdelkader_69182,

Can you please try to ping against the primary to check for any latency issues:

ping sandbox-shard-00-00-zh5bt.mongodb.net

Are you able to connect to the cluster and query the data using Compass?

Thanks,
Sonali

I don’t have any problem using compass.

Hi @Abdelkader_69182,

Please check your network connection and then reconnect to your cluster and query. It should work.
In case the same problem persists, please let me know.

Thanks,
Sonali

My internet connexion works normally, I can do anything else withou a problem.
But the same problem persists for the Mongo shell…

Hi Abdelkader,

Thanks for the additional information.

This looks like it is a networking related issue.

I would like to check some settings on your client machine. Could you please provide me with the output of the following from your command line:

reg query HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v KeepAliveTime

Please also provide me with the exact version of the mongo shell you are using.

Thanks,
Barry

Hello,

thank you for your help.
The command sends back : “error: key name not valid”
And I use the MongoDB shell version v4.0.8
