Newbie cannot reach the server.

Hi,

I am new here. I have already added an A record on Google Domain DNS setting, and also open HTTP, HTTPS, SSH and ICMP ports. Now I can ping or ssh my domain, and browse by ip address successfully, but failed to browse by domain. Who can help me to solve that?

Hey friend,

It depends somewhat on the error you’re receiving. I propose that it’s just DNS propagation though. I like this explanation:

Being able to ping/ssh by domain rather than IP makes me second guess my instinct here, but I’ve seen browsers cache DNS on their own, regardless of the system OS.
