Unable to access repository when updating Messaging Gateway

Products

• Messaging Gateway

Issue/Introduction

When attempting to update the Symantec Messaging Gateway, the update command returns

Unable to access repository.

Cause

Messaging Gateway is unable to download the available version descriptions from the download server swupdate.brightmail.com. After 60 seconds the update attempt times out and generates an error.

This may be caused by a variety of network related issues including

• Firewall disallows connnections to the download server
• Proxy server or other network device is using TLS inspection

Resolution

1. Ensure that Messaging Gateway is allowed to connect to swupdate.brightmail.com on port 443 through the network firewall
   1. Log into the SMG command line as admin
   2. Run curl https://swupdate.brightmail.com (note: curl is not available from the admin CLI on versions prior to 10.8.0)
2. Ensure that TLS inspection is not used for outbound HTTPS connections from Messaging Gateway
