Oh, you have 3 IP addresses in your DNS. Looks like you had a "Domain Forwarding" feature setup. Either now or in the past.
Your DNS should just have the one public IP address for your nginx server.
e-selector.com. 600 IN A 91.64.135.180
e-selector.com. 600 IN A 15.197.142.173
e-selector.com. 600 IN A 3.33.152.147
It is funny coincidence. I saw one just like this earlier today with Wild West Domains registration (a part of GoDaddy I think).
Anyway, please see this post for further help
