# Testing and troubleshooting the sync

Follow these steps to test and troubleshoot your configured sync between PingOne and PingDirectory.

## Steps

1. Test the sync:

   1. Run the sync with the following command:

      ```
      /opt/<PingDataSync>/bin/resync -p  <sync_pipe_name>
      ```

   2. (Optional) If the sync results in any errors, see the `/Ping/<PingDataSync>/logs/tools/re-sync-failed-DNs.log`.

   3. (Optional) If you receive an error that includes `Cannot connect because: The connection to server localhost:11389 was closed while waiting for a response to a bind request SimpleBindRequest(dn='cn=dmanager').`:

      1. In the PingDataSync admin console, go to **Configuration → External Servers → ServerPD\_PDtest**.

      2. Update your password.
