I recently acquired some nanopc t4, I wanted to install casaos, openmedivault, friendlywrt, pihole, and things like that, it turns out that no matter what operating system I install, armbian, ubuntu, lubuntu, debian, or the official ones, I never have access to the installed services, that is I can not access casaos from another pc, as if there was a firewall that blocks incoming connections, I only have access via ssh, if I pin to the ip address (192. 168.0.31 for example) all good, there is no firewall installed, with all the systems the same thing happens to me, in all the nanopc, I only have access from the same nanopc, that is to say, 127.0.0.1, but it is impossible to access from another pc to the address 192.168.0.31, it is as if the nanopc did not exist, what am I missing, I know there is something that blocks it but I cannot find it.
