Hi @Pyra_Metrik,
If you’ve checked with the Atlas in-app chat support and they’ve advised no issues were identified on the Atlas cluster side at the time of the error messages, I would also recommend checking with Vercel support. There was another mention of this previously on this post as well.
Depending on your cluster tier, you might be able to check the mongod logs to see the client metadata as well to determine if connection was ended from the application side possibly.
You can perform the same troubleshooting step mentioned in my comment by connecting from a different client perhaps outside of Vercel for trying to narrow down what the issue could be.
Regards,
Jason
