CPanel/WHM Unknown License File Error - cpanel

Question

So my issue is like the title suggests. However I have tried the following suggestions from this page (https://documentation.cpanel.net/display/ALD/Installation+Guide+-+Troubleshoot+Your+Installation#InstallationGuide-TroubleshootYourInstallation-Licenseerrors) with no results.
1.) curl -L http://cpanel.net/showip.cgi (shows my ip address on the server for use on the verify.cpanel.net script), this can be verified also here... (http://verify.cpanel.net/index.cgi?ip=xxx.xxx.xxx.xx) (I don't like showing my IP, but trust me it was verified.)
2.) /usr/local/cpanel/cpkeyclt
Updating cPanel license...Done. Update Failed!
Error message:
A License check appears to already be running.
Building global cache for cpanel...Done
So the above didn't work.
I then tried these commands.
3.) /usr/local/cpanel/etc/init/stopcpsrvd and then /usr/local/cpanel/scripts/upcp --sync to attempt to resynchronize.
This appears to successfully run but I still get the same error. Attached below is the error message I get when I attempt to login to WHM.
4.) I then tried running rdate -s rdate.cpanel.net as suggested in some other posts to have the times match up and then when I run (/usr/local/cpanel/cpkeyclt) it seems to time out and nothing ever happens.
Looking at the logs for the cpanel license (/usr/local/cpanel/logs/license_log) I see this.

Answer 1

It turns out the answer was IPTables. Before that it was the rDate command that was necessary to fix it, but my IPTables was blocking the connections.
To temporarily disable your firewall do this.
iptables-save > /root/current.ipt
iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT
iptables -F INPUT; iptables -F OUTPUT
ping -c 3 google.com
iptables-restore < /root/current.ipt
rm -f /root/current.ipt
The first command saves a copy of your firewall settings.
The next 2 commands make it so all input/output are allowed (for outgoing and incoming connections)
Finally test by pinging the ip address that was giving the issue for cPanel in your log file.
If it works that means the update license command will work.
Simply run:
/usr/local/cpanel/cpkeyclt
and you are good to go.
You can restore back your rules by using the last 2 commands if you want:
iptables-restore < /root/current.ipt
rm -f /root/current.ipt
Be warned that you will be blocked again, unless you fix the firewall.
