Solution​

  1. In the top navigation bar, click Sync Settings > Exception Log.
  2. Click SIDECAR tab.
  3. Check the exception stack trace in the Operation column to see the host-related information and confirm whether the connection failure is caused by wrong host information, incorrect account or password or network issues (such as incorrect IP address or port, firewall blocking).
  4. Login to the host of Sidecar container, and then directly connect to the database to see if it can be accessed.
