Have created a minecraft server everything can also join via the domain of no-ip but no one from outside because my port is shown as open but with port scanners as closed. I have public ipv4 address from router connected to no-ip. Made port release in Panda antivirus and Windows Firewall Defender.
No-IP is only DynDNS, isn't it? You also have to forward / release the port in the router.
I didn't mention ups habs sry
