(dedicated server) trying to put them public. need help.

[Okonnot]

Hello everyone I have a question to pass the server in public on a dedicated server,
I did absolutely everything that was asked (have a dns on ovhcloud with dedicated server)
I rechecked the ports ,the "host" file etc but when I try to connect with a pc I get stuck in the choice of server...
anyone had a similar problem ?
my server is on ovhcloud
