I suppose it could be a weird routing issue with your DNS settings or a modified /etc/hosts file? Can you flush the DNS cache and try again? You can also grep for that address across all configuration files in the conf directory to see if it’s persisted anywhere. If you grep from a directory up ($NIFI_HOME), the only place you should see it is in the log file documenting the error.
