These MongoDB errors starter appearing: MongoNetworkError: connect ETIMEDOUT and MongoServerSelectionError: connect ETIMEDOUT

I have been making a React and NextJS App for a month now and I use MongoDB for the database. I use it through MongoDB Atlas. It is also just the free version.

I use NextJS’s api folder for the backend.

I have had no problems at all and everything works just fine. Suddenly I have started to get these errors:

error - MongoNetworkError: connect ETIMEDOUT 18.166.253.100:27017

  [Symbol(errorLabels)]: Set(1) { 'ResetPool' }

As well as this one:

  },

  [Symbol(errorLabels)]: Set(0) {}
}

I dont think the problem is with my code and how it receives the data since even an old project from a React and NextJs course started to get this issue.

Im not using a vpn or something to change my IP address either.

Does anyone know what causes this? Is there a setting or option that could have changed that I need to fix?

Is MongoDB currently under maintenance or full?
Any help would be greatly appreciated. Feel free to ask any questions.

Thank you!
