Cant access to Mobile Access Portal, Browser keeps loading without giving an error

Look under /opt/CPcvpn-R75.20/log/cvpnd.elg for the problem reason,
In my case it was showing
Exception: open("/opt/CPcvpn-R75.20/conf/includes/CustomRulesAfter.conf") failed - No such file or directory - CVPND aborting
manually create the file or files,
touch /opt/CPcvpn-R75.20/conf/includes/CustomRulesAfter.conf
touch /opt/CPcvpn-R75.20/conf/includes/CustomRulesBefore.conf
and do  a cvpnrestart
Also check licenses on both cluster members...
