Unable to Access Control Center Web Console (Port 443 Access Denied)

Products

• Messaging Gateway

Issue/Introduction

Customers are unable to access the Control Center web console via any web browser.

Symptoms

• The web interface fails to load, typically showing a "Connection Refused" or "Page Cannot Be Displayed" error.

• Running a local telnet command on the Control Center CLI to its own IP address on port 443 results in an "Access Denied" or "Connection Refused" error.

Resolution

To assist our backend team in identifying the root cause, please collect diagnostic logs directly from the Command Line Interface (CLI) and provide them to Broadcom Support.

1. Log in to the Control Center CLI using your admin credentials.

2. Execute the diagnostic command to gather system logs.

3. Transfer the resulting file to an external FTP or SCP server using the commands:

   diagnostics --logs all ftp://user:password@[:port] /path
   diagnostics --logs all scp://username@host/path

Support Process

Once logs are collected:

1. Open a support ticket via the Broadcom Support Portal.

2. Upload the diagnostic logs to the ticket for analysis by the engineering team.
