Summary:
When clicking on the Unsubscribe link in an NFA Scheduled email, it fails because the link is using an IPv6 address, you may see the error below:
Solution:
1)RDP to your NFA console server.
2)Run the following command using the IP address of the NFA console server in place of the x.x.x.x
mysql -P3308 reporter -t -e "update general set value='x.x.x.x' where attribute='WebSite.Address';"
3)Verify the IP address is set correctly with the following command:
mysql -P3308 reporter -t -e "select * from general where attribute='WebSite.Address';"
4)Recycle the 'Netqos ReporterAnalyzer Manager Service' and your next scheduled email show contain a link with the IPv4 address you entered in step 2.
