Silverfast Software Registration Blocked

I am running Clearos Community 7 as my firewall.

I have Gateway Antivirus, Intrusion Detection, and Intrusion Prevention installed.
Here is a list of installed services in case I missed something.

nscd
dnsmasq
clearsync
snort
snortsam
arpwatch
slapd
postfix
sshd
suvad
system-mariadb
rsyslog
crond

I am trying to register and check for updates for SIlverfast 8 SE software om a Windows 10 system. All this is done from within SIlverfast. When I try this then Silverfast says:

-----------------------------------------------
Currently loading content from the internet...

If this message remains there is a problem with the internet connection and/or firewall setting.
----------------------------------------------
It just sits there forever waiting to connect.

The PC has McAfee on it. I turned off Mcafee firewall and real time scanning but that did not help.

I then turned off Gateway Antivirus, Intrusion Detection, and Intrusion Prevention but that did not help either.

The following ar ethe services that are currently turned off.

nscd
snort
snortsam
arpwatch
slapd

Any idea how to allow SIlverfast to connect so I can register and update it?

Thanks
