Timeout on MongoDB Atlas connection

[Pierrick]

Hello,

Since yesterday (2018-10-22 at about 7PM UTC), we have a reachability issue when trying to connect from a nodejs app : "error MongoNetworkError: connection 104 to xxxxxxx.mongodb.net:27017 timed out".

It happens every 20 mins or more often sometimes (10, 5 or 2 minutes).

We didn't change anything in our side ? Is there something we can do ?

Cheers,

Hi Pierrick,

Since yesterday (2018-10-22 at about 7PM UTC), we have a reachability issue when trying to connect from a nodejs app : “error MongoNetworkError: connection 104 to xxxxxxx.mongodb.net:27017 timed out”.

From the error message, it looks like there’s a network issue from the machine that’s hosting your app to Atlas. Can you confirm that you can connect using the mongo shell without any issue? Is the issue intermittent, or are you consistently cannot connect to Atlas? What is your Atlas instance type?

Please note that if you’re using Atlas, you can open a support ticket at MongoDB support page. If this issue is still unresolved, I would encourage you to open a ticket.

Best regards,
Kevin

Hi Kevin,

The issue seems to be resolved without any change on my side.

It was intermittent during about 2-3 days.

Mongo shell used to report : 'Dropping all pooled connections to xxxx-shard-00-00-yyyy.gcp.mongodb.net:27017(with timeout of 5 seconds)'
Similarly, mongostat reported something like 'No data recieved' only for the primary host
I use a free tier instance for the moment.

Regards,
