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

Solution 3: Verify Credentials

  1. Try logging into device with credentials stored in GCXONE
  2. If login fails, update credentials in GCXONE:
    • GCXONE → Devices → [Device] → Edit → Update credentials
  3. Save and test connection

Solution 4: Check for IP Address Change

  1. Verify device IP address hasn't changed
  2. If IP changed, update in GCXONE device settings
  3. Consider assigning static IP or DHCP reservation

Expected Result: Device status shows online/green in GCXONE.

Video/Streaming Issues​
