I'm trying to connect my Spring Boot application to MongoDB but I am getting the following error:

I created the connection to the database through Atlas MongoDB.

I don't know how to solve this problem.

Thanks in advance.

  • It's hard to read that stacktrace with the current formatting. You might want to reformat it as a code snippet to get intendation and longer lines with side scrolling (makes it easier to spot actual stack trace lines). Commented Sep 16, 2020 at 21:50
  • You might need to whitelist the IP from which you are trying to connect to your MongoDB cluster. Documentation Look at this example Commented Sep 16, 2020 at 22:28
  • Are you able to connect to the cluster from any other client programs (e.g.,mongo shell or Compass)? Commented Sep 17, 2020 at 1:13

This seems to be a connection issue with the database from the error trace. Can you check if the port 27017 blocked by your firewall. You need to open the outbound and inbound for this port in your firewall.

Steps for Windows:

  1. Go to Firewall
  2. Advanced Settings
  3. Inbound Rules
  4. Create a new rule with New Rule under Actions tab
  5. Select Port
  6. Select TCP and specify port no (27015,27016,27017)
  7. Allow the connection
  8. Click Next
  9. Add name for new Rule Finish
  10. Follow the same steps for Outbound Rule. Once done, restart your system.
