Hmm, if there’s no apparent firewall control in Hostinger, it might have some restricted network policies in place by default. Let’s try testing the server’s actual connectivity to see if it’s reachable by players at all.
You’ll want to use an online tool like CanYouSeeMe.org or any port checker to verify if port 25565 is open and accessible. Use the server’s public IP and the Minecraft port.
Give that a shot and let me know if it’s all green lights—or if it’s frowning at us.
