The server's hostname can also influence router configurations.
The server's hostname can also influence router configurations.
I manage a Minecraft server from my home using an internet plan that assigns one public IP per household, so the same public IP appears on both my server and my dad's computer. Recently I renewed the No-IP hostname and tried searching it in Chrome—my router login appeared. You might want to explore methods to restrict access to your router login when using the hostname.
Have you attempted to reach this from a different network? Testing inside your local area will work with the public IP, but using a phone on 4G might not connect at all. NOTE: I’m using a VPN through No-IP DDNS. From LAN I access my gateway’s login, but outside the network it’s blocked by the firewall—WAN ports 80 and 443 are disabled by default. You’ll need to manually permit access in the firewall for external reach.
As suggested by @Oshino Shinobu, explore sources beyond your existing network. If successful, restrict HTTP and HTTPS traffic from external devices to your router.
