Hello! Requesting guidance in setting up MongoDB Atlas as a source on Azure Data Factory. Our connection test as a linked service passes and we are able to preview collections when attempting to set up the pipeline. However, every run fails with

ErrorCode=MongoDbConnectionTimeout,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=>Connection to MongoDB server is timeout.,Source=Microsoft.Connectors.MongoDbAtlas,''Type=System.TimeoutException,Message=A timeout occurred after 30000ms...

Hello Jake ,
Since you are able to see the data in preview, that's means the connection the DB is just fine. I also see that that you are getting a timeout, I suggest you check as to what is the volume of data which you are trying to pull? Try with a small set and see if that works.
Thanks

Hi, Himanshu. We applied a filter to our pipeline to only pull a single record but still had the timeout issue. It looks like ADF fails to connect to Mongo when we attempt to run a pipeline even though we can preview the collection. The timeout occurs before ADF is able to read the first byte of data.

I am having this same exact issue
Same Issue - Preview / Filter work fine. Debug pieline run fails with timeout
Okay so I discovered the issue and it is that the AutoResolveIntegrationRuntime will change regions on you so you either have to create your own integration runtime and whitelist that IP address in mongo or set up a peer connection.
