Is the ePO network traffic scanned by a web gateway (which is capable of scanning HTTPS traffic) ?
If so Software Manager will not work due to a false certificate ...
I've confirmed the task fails with this message either using our proxy server or bypassing around the proxy. My network team has looked through their logs for all traffic to/from the ePO server and have confirmed there are no packets being blocked.
I have also encountered similar issue.
I am using Microsoft Forefront TMG 2010 with HTTPS inspection disabled.
Valicert certificate has been imported to epo.
But the error still occurs.
The logs from TMG show no packets being blocked.
I cannot open https://epo.mcafee.com
Is it due to certificate validity?
it is currently not possible to get around this issue without disabling the SSL Scanning on your gateway.
You cannot import the gateways SSL certificate in a way to make epo use this one instead of epo.mcafee.com for Software Manager.
regarding the above comment
I have need to explain and justify this certificate checking to our IT Security guys to allow Software manager though the Firewall etc.
Is there any documentation that you are aware of, which explains the process?
afaik no - we got the info directly from McAfee support.
