No access to the site by domain, what's wrong?

Question

Google Chrome

I have a site created as a microservice with built-in jetty. It is located on a virtual server on CentOS 7. DNS servers are configured for my IP and those support checked everything is working fine.
On the first day of using the server, it came both by IP and by domain.
Now, either on the domain there is no access at all, or there is access for everyone except my PC (my SP does not enter via wifi from a smartphone). If you change the IP access is excellent. The most frustrating thing is that, for unknown reasons, it may become inaccessible to everyone. What could be the problem? there is no firewalld on the server.
UPD: An interesting feature in firefox / IE opens, but chrome (and others on its core) have neither desktop nor android
UPD2: And then I booted up on Linux and everything opens.
UPD3: Everything started to work correctly without interference on the server and immediately stopped having access for everyone except me

Answer 1

The problem is unstable DNS servers, never trust those support)

Answer 2

try ipconfig /flushdns

Answer 3

can you link to the site? and then there are no telepathic admins)
