I am attempting to connect a PayloadCMS GitHub Repo to a MongoDB instance both hosted on Railway. However, I am unable to make a connection using the private address generated by railway ${{ MongoDB.MONGO_URL }} and receive the below error message:
Error: cannot connect to MongoDB. Details: getaddrinfo ENOTFOUND mongodb.railway.internal
This implies that the error is related to the connection string, however, when I attempt to make a connection to the MongoDB instance using the public address and Mongo Compass the connection is successful. More bizarrely if I try to connect to an Atlas Cluster using the same source repo in Railway the connection is also successful.
I am happy to use an Atlas Cluster but I would prefer to host everything on Railway but need to be able to connect to the MongoDB instance via the private address.

Hi there, could you make sure your app service has the correct reference variables for your MongoDB db setup? Our docs on connecting to Mongo might help https://docs.railway.com/guides/mongodb#connect

Hi, thank you for your reply.
The connection string produced by the reference variables are below:
Internal
mongodb://username:password@fray-cms-storage.railway.internal:27017
External
mongodb://username:password@yamabiko.proxy.rlwy.net:34692
I can connect to the railway MongoDB instance using the external address on my local machine (using the same repo).
I can also connect to an Atlas cluster on railway (using the same repo).
But I cannot connect the railway MongoDB instance using the internal address on railway (using the same repo).
Is there something I can do to fix this?

Hey, is your app correctly using our private network? I'd recommend checking out our docs on https://docs.railway.com/guides/mongodb and https://docs.railway.com/guides/private-networking in case you might have something misconfigured
