When I ping my Lightsail static IP, return just once then timeout. So I cannot using my domain name
-
My domain DNS setting is below.
-
My Lightsail instance domain setting
-
My Lightsail Domain setting
-
Lightsail Domain A record
-
Domain assigned to StaticIP(the instance's public IP)
Is there anything wrong above settings? I could not access the instance using my domain name for 4 days.
Please let me know what I have to do.

Hello.
Since the name can be resolved using the dig command, there is probably no problem with the DNS settings.

I can access it with the HTTP status 200 using the curl command, so I think the access problem has been resolved.
curl http://conebeamcenter.com -I

It can also be accessed using HTTP using a browser.
If you cannot access it, please try deleting your browser's cache.
Try configuring your Lightsail firewall to allow ICMP packets.

Thank you so much. The issue is resolved. :-)
Hi, You may want to delete the screenshots from your question since they show a lot of details about your resources and setup.
Hello,
Can you delete the cache in your browser and try to connect again. The website "http://conebeamcenter.com/" is accessible via domain name as well as public IP address.
ICMP Ping is a supported protocol in Lightsail Firewall. I believe you mean, the user has NOT configured ICMP ping on their instance.
