Hi All,
We have attempted to upgrade 2 install with WHMCS V5.3.12 via whmcs_v5311_incremental_to_v5312_patch.zip and now both sites are reporting reporting a license error.
We have ran curltest.php as per http://docs.whmcs.com/Licensing#No_Connection_Error article and it is advising that someone on our server is trying to bypass licensing. This is a serious allegation.
I have verified with Google Servers, Cognet Servers etc and all DNS servers are reporting that whmcs.com resolves to 104.20.20.8 and 104.20.21.8 which according to WHMCS is wrong.
Also tried https://www.whatsmydns.net/#A/whmcs.com
Anyone else had issues?
