Solution 2: Check Credentials and Settings

  1. Verify username and password are correct
  2. Ensure user account has administrator/sufficient permissions
  3. Check if device requires HTTPS (try both HTTP and HTTPS)
  4. Verify port number is correct (check device documentation)

Solution 3: Verify Firewall Configuration

  1. Check device firewall settings allow incoming connections
  2. Verify GCXONE IP/network is whitelisted on device (if applicable)
  3. Check network firewall rules between device and GCXONE
