@austinsonger It's api.cloudron.io (not cloudtron ).

Can you also try these 3 commands:

• host api.cloudron.io
• host api.cloudron.io 8.8.8.8
• host api.cloudron.io 127.0.0.1

[austinsonger]

@girish typo. .

@austinsonger It seems outbound UDP port 53 itself is not working. Do you have some firewall or something else in place? The command host api.cloudron.io 8.8.8.8 directly contacts Google DNS servers via UDP port 53 but it's not working as seen from your output.

[austinsonger]

My outbound is completely open. I'm using AWS defaults. The only ports I have change is TCP ports related to the email.

[austinsonger]

There was a security update that happen on the dashboard and pretty much afterwards it stopped connecting to the Appstore. I'm going to create a outbound rule for UDP 53 to see if it forces it or something.

@austinsonger Does ping 8.8.8.8 work?

[austinsonger]

@girish said in Try to go to App Store, but it just times out.:

host api.cloudron.io 8.8.8.8

It looks like creating a rule for outbound UDP 53 worked, but that's weird cause it was already setup for All ports outbound to be open.

ubuntu@ip-172-31-1-28:~$ host api.cloudron.io 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases: 

api.cloudron.io has address ##.#.##.###
ubuntu@ip-172-31-1-28:~$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

when I do this ping it just sticks there and doesn't complete.

[austinsonger]

Should I try restart the server now? Just to see if that resolves it now.

This section just continues to load until it timesout as well.

Strange. The default as you said is to have All ports open. But if this is the case, can you also add HTTPS port there (tcp port 443) ? That will enable the appstore calls to work. In addition, for ping to work, you have to add ICMP port (this is a special protocol port like tcp/udp)

[austinsonger]

Yup. This makes no sense.
