Web browser cannot connect to the Control Center web interface

• Messaging Gateway

Issue/Introduction

When attempting to connect to the Messaging Gateway Control Center via a web browser the browser returns an error page indicating that it could not connect to the SMG system.

Resolution

To confirm that the Control Center web interface is accepting connections:

1. Log into the Messaging Gateway command line interface (CLI) as the admin user
2. Confirm that the Control Center web application server is running
   service controlcenter status
3. If the service is not running, start it
   service controlcenter start
4. Confirm that the web application server is listening to the expected port
   cc-admin --status
   or
   netstat -lt
5. Connect to the Control Center and request the login page from the command line
   Note: earlier releases of Messaging Gateway do not have access to the curl command from the command line and will need to use telnet for connection testing
   curl https://127.0.0.1/brightmail/

If the Control Center is running and accepting connections but your web browser still cannot connect to it:

1. Reset the access control list from the command line
   delete bcchostacl

If you still cannot connect, check with your network or firewall team to confirm that firewall rules are not disallowing connections from your network or IP address.
