Here are some possible issues with this case:

  • Check your IP address is whitelisted with your MongoDB client
  • Check your connection URI once again to check the possible error with that.

Please check this other problem and solution. link

I have faced the same issue, whatever I done is:

  1. restart my node server.
  2. change my database user.
  3. change my network and waiting sometime.
  4. then tried to connect.
  5. this time mongo connection was fine.

N.B- you can check your connection URI too, if its ok. then try with a different network.
