Thanks for using Bitnami. According to the DNS checker whatsmydns.net, your DNS information is not yet fully propagated. According to it, your DNS entry pointing to that IP address is only configured in one region, while is pointing to multiple IP address (a load balancer probably) in the rest of the regions.
DNS changes can take up to 48-72 hours to fully propagate. Can you take a look at the DNS tool and run the bncert tool again once all the DNS regions have your DNS entry updated?
