Why is there a 502 error in this case?

Question

Network administration

Hello! We make a server in minecraft with friends. I purchased a domain and a vds server, uploaded a server to it, now I need to install a website.
Dedik's ip: 185.213.209.198, the Apache start page is available on it if you go in the browser, and if you add this ip to minecraft - the server.
If I created a DNS record A and pointed this ip into it in the domain, should I have both the site and the server? Now the domain ( infinityworld.ru ) has a 502 error, why? How can I put several sites at once on one VDS server (I heard somewhere that this is possible)
I didn’t work much with Dedicated servers before, I always used regular Wirth hosting, I decided to fix the mistakes and do something for myself without fear of mistakes)
Help please)
