Issue/Introduction

 Your Notification Server (NS) was communicating with agents via HTTP and you reconfigured the communication method to use HTTPS. The IIS was then configured to require SSL and the codebases were changed to publish via HTTPS. However even after running the NS.Refresh Packages and the NS.Update Distribution Point tasks the ULM (Unix Linux Mac) agent is failing to install reporting the following error:

Checking Client connectivity and free space - Failed

In status report > [View log] you see:

INFO: SHA 256 Integrity check succeeded.

INFO: Getting Package : http://<<NS FQDN>>/Altiris/NS/NSCap/Bin/Unix/Agent/Mac/x86/package-manifest.xml into temp dir /opt/altiris/notification/nsagent/.tmp_inst

INFO: Failed getting package, Msg: HTTP server returned an error

ERROR: Package download failed, Agent Install failed

Environment

ITMS 8.x

Cause

The package link is being cached

Resolution

Try the following:

1. Open CMD as Administrator on your SMP Server and run iisreset
2. Open Services.msc on your SMP Server and restart the Altiris Service

That will clear the cache and the link should then be replaced with HTTPS. The NLM agents should now be installed successfully via a push install.
