Issue: The LoadMaster is unable to download the WAF rules and is reporting that the ASLI server is unreachable. A packet capture will confirm that alsi.kemptechnologies.com cannot be reached.
This is usually the case when there is a local search domain is configured on the LoadMaster.
The search domain is configured under System Configuration > Network Setup > Host & DNS Configuration.
Also check if alsi.kemptechnologies.com (188.8.131.52) and alsi2.kemptechnologies.com (184.108.40.206) can be resolved by going to System Configuration > Logging Options > System Log Files > Debug Options > Ping host, and change the Interface to automatic.
Remove the set search domain and re-try the download.
