you can confirm if it's working by checking visitor ips logged in your site's access_log at
/home/nginx/domains/domain.com/log/access.log

note as centmin mod nginx users a buffer cache ~256k in size for 60 seconds for writes to access_log for performance, log entries are not realtime unless you do an nginx restart which flushes writes from buffer cache to
/home/nginx/domains/domain.com/log/access.log

list last 10 lines of /home/nginx/domains/domain.com/log/access.log

Code (Text):

tail -10 /home/nginx/domains/domain.com/log/access.log

you can browser your site first and look for log entry for your ISP ip

if you are still getting redirected to main hostname, then it won't show up in /home/nginx/domains/domain.com/log/access.log

have you also tried clearing browser cache, reboot your local pc before seeing if a redirect is cached in your browser ?
