Introduction

This document describes how to troubleshoot the error “Either API server is not started or is unreachable” in Secure Email Gateway (SEG) Next-Gen GUI.

Prerequisites

Starting with AsyncOS 11.4 and continuing with AsyncOS 12.x for Security Management Appliance (SMA), the web user interface (UI) has undergone a redesign as well as the internal processing of data.

Requirements

Cisco recommends that you have knowledge of these topics:

- Secure Email Gateway (SEG)

- Security Management Appliance (SMA)

- Web user interface (UI) access

Components Used

- SEG on version 11.4 or later releases

- SMA on version 12.x. or later releases

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Problem

Unable to access the Next Generation web interface and getting the error 'Either the API Server is not started or is unreachable'.

Solution

Step 1. Verify that AsyncOS API HTTPS is enabled in the Management IP of the Secure Email Gateway/Security Management Appliance

Note: For Cisco Secure Email Cloud Gateway, contact TAC to review the IP configuration.

Step 2. Confirm the hostname configuration

Ensure the appliance hostname in not in use in any other configuration or appliance, run the sethostname command to verify it or change the configuration if needed.

sma.local> sethostname

[sma.local]>

Step 3. Verify network access

For Next Generation GUI, is required to allow trailblazer and port 443.

Run the command trailblazerconfig status.

sma.local> trailblazerconfig status

trailblazer is not running

sma.local> trailblazerconfig enable

trailblazer is enabled.

Step 4. Access the Next Generation GUI

Access the Next Generation web interface.

If the issue persist contact Cisco TAC.
