ONB server using TCP port 580 has some authentication issues

Hello all,

I have an issue where client application can access RSTP stream port 554 but port 580 shows some authentication problems

For context, I am using Xprotect Corp 24.1a

My deployment is in AWS and we are using 2 NLBs 1 port 554 terminated TLS and 2nd load balancer using TLS port 580

The connection itself was confirmed to connect to the ONB

Both port 554 and 580 are using the same Basic user with the same Roles (with limited access to certain features)

My question is

What are the Roles settings or any other setting change I should change to allow for access specifically for port 580?

Hi Andrеs,

Thank you for contacting us. Here are some recommendations and guidelines to verify in your setup:

In the Management Client, the default Milestone Open Network Bridge (ONB) port settings are:

  • ONVIF port: 580
  • RTSP port: 554
  • (If you change these ports to avoid conflicts, make sure to also update the ONVIF client connection URI.)

For user and role configuration:

  1. Create a basic user in the Management Client.
  2. Make sure that this user is assigned to a role with the necessary camera viewing permissions.
  3. On the role’s Overall Security tab, grant permissions for all the Milestone Open Network Bridge security group.
  4. In the ONB tray manager, go to Manage ONVIF client users and verify that this user is added.

This should ensure that the ONVIF client has the correct authorization to access streams through the bridge.

A couple of clarifying questions to better understand your setup:

  • Is the ONB installed on the same server as the Management Client, or on a separate machine?
  • Which version of ONB are you running (for example, 24.1a)? If possible, try upgrading to the latest version (2025 R2) and see if the issue persists.
  • Can you capture and share a Wireshark trace of the ONVIF traffic on TCP port 580 so we can review the authentication handshake?

Additionally, please check the ONB service status (the tray icon should be green when running) and review both the ONB and RTSP logs via the tray manager. These often provide more detailed error information that can help narrow down the issue.

I hope this information is helpful. Please don’t hesitate to reach out again if the problem persists, ideally with some additional details so we can assist further.

Kind Regards,
