If you solved it, just reply that. If you did not, provide some information for everyone to help you with. This photo is just chrome's timeout page. Hmmm... I suspect you might have mixed up local (LAN) access to a TrueNAS with an IP of, say 192.168.1.100, with how one can access a server from across the internet, witch requires to know your
public IPv4 address and to
port-forward your TrueNAS in the router. I don't know what the situation is, though, so don't feel offended. I just make the best guess I can with what I am given. Have a good day.
