Failure to connect to mongoDB out of the blue

I’ve made no changes recently. My NodeJS app can no longer connect to mongoDB for some unknown reason. Last known communication between API and DB was on March 2. If I run my API server on my local machine, I can connect to my DB just fine. However, when run on the Fly machine, no bueno. I get this error:

Error connecting to MongoDB: Could not connect to any servers in your MongoDB Atlas cluster. One common reason is that you're trying to access the database from an IP that isn't whitelisted. Make sure your current IP address is on your Atlas cluster's IP whitelist: https://www.mongodb.com/docs/atlas/security-whitelist/

Any ideas? The error is thrown on this:
await mongoose.connect(process.env.MONGODB_URI);

MongoDB is setup to accept connections from anywhere. (0.0.0.0/0)

I’ve changed nothing and it’s started to work again. I’m thinking probably a temporary outage or hiccup from fly or mongo. All good!
