Unable to Connect Foundry to MongoDB Atlas (Free Edition)

Ask the Community
1

Hi Palantir Community,

I’m encountering persistent issues trying to connect Foundry to MongoDB Atlas. Despite trying multiple connection strategies, I keep getting connection timeout errors. Here’s what I’ve tried so far:

Attempted Strategies:
Atlas Connection Type:

  • Host: account1.abcd.mongodb.net (in this format)

  • Authentication

  • Add network access in Mongo with foundry IP

  • Connection options: ssl, retryWrites, w=majority

Common Error Message:

MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches ReadPreferenceServerSelector{readPreference=primary}.

*The connection works fine in using standard MongoDB connection string (not with foundry)

Questions:

  1. Are there specific network/DNS configurations needed for Foundry to connect to MongoDB Atlas?

  2. Is there a recommended connection strategy for MongoDB Atlas in Foundry?

  3. Are there any known limitations or requirements when connecting Foundry to MongoDB Atlas?

Any guidance or best practices would be greatly appreciated.
