My app has stopped working

Apparently my app has stopped working, the error appears:
const serverSelectionError = new ServerSelectionError();

I cannot connect using MongoDB Compass and when trying to view my collections in the database on the website, the error appears:
“An error occurred while querying your MongoDB deployment.
Please try again in a few minutes.”

Can anyone help me?

Hi :wave: @Leonardo_Guimaraes,

Welcome to the MongoDB Community forums :sparkles:

Are you referring to an error encountered when accessing a database deployed on MongoDB Atlas using the Data Explorer?

You mentioned your app stopped working, can you clarify if it was working before and suddenly stopped working without any changes being made from the application end?

I cannot connect using MongoDB Compass

Were you able to connect before using MongoDB compass?
