Unable to ping my dedicated server with my domain from home. (Using Ubuntu 16.04 LTS)

Virtualmin
1

Hi, I have setup Virtualmin on my dedicated server and got all the DNS working right (I think).

Anyways, i have this issue, i am not able to ping my dedicated server from my house, when i ping power-gaming.win i get timeout, but when i connect into ssh and ping the domain, i get the domain with the correct ip address assigned to it. Now i have Firewalld up and running all the ports open and tried to ping the domain name from my house, still not pingable - so i disable the firewalld and tried it again, still can’t ping the domain from my home. when I type in https://power-gaming.win:10000 i get this,

Hmm. We’re having trouble finding that site.

We can’t connect to the server at power-gaming.win.


Though when I type in https://158.69.243.125:10000
it does work, and i can be able to ping it from home also. I did with both IP Addresses and they work internally and externally.

i did a dig power-gaming.win here is the request in return.

when i use tail -f /var/log/syslog i do not get any errors.
i checked the /var/log/virtualmin for errors and i get CA Cert Errors, but it doesn’t tell me why i cannot ping the domain name from my home.

Here is my DNS Records:

$ttl 3600 @ IN SOA ns1.power-gaming.win. root.ns1.power-gaming.win.

Thanks, Rikor420

Howdy,

Hmm, I don’t seem to be able to do a DNS lookup on your domain.

However, if I telnet to any of the ports on the IP address you shared above, I can access the ports.

I think the issue to solve is to determine why these DNS lookups aren’t working – you can see the issue by going to this site here:

https://intodns.com/power-gaming.win

You’d want to be sure that BIND is listening on port 53 UDP.

Also, if your server is behind a NAT router, be sure that port 53 UDP is being forwarded to your server from the router.

Also if using csf or other firewall port 53 is not everytime default open for the dns… you sure you opened all ports for testing.

But thats is not the problem here, so only for other readers finding this, port 53 udp has to be open in firewall.
You have nameserver problem as andreychek pointed out in link

Ok will check once again on the Port 53, and let you know.

ok i opened up port 53/udp.
I noticed when i opened up 53 it points to 127.0.0.1:53 < = is this correct?
my host is

127.0.1.1 power-gaming.win power-gaming
127.0.0.1 localhost.localdomain localhost
158.69.243.125 power-gaming.win power-gaming

it this correct?
