Understanding DNS & DDNS

telnet results in

[~]── - telnet 192.168.1.1 443
Trying 192.168.1.1...
telnet: Unable to connect to remote host: Connection timed out
[~]── - 
[~]── - telnet 192.168.1.1 80
Trying 192.168.1.1...
telnet: Unable to connect to remote host: Connection timed out
[~]── - 

So nothing seems to be listening on port 443 or 80.

I might have to have a look at the gateways or firewall rules but afaik, I am not blocking anything on the LAN network.
