The IPnumber associated with padmahasa.ddns.net (103.228.221.102) is not reachable via ping or traceroute. A traceroute ends at: 43.254.160.42.static.belltele.in (43.254.160.42) Additionally, attempting to telnet to either port 80 or 8080 on 103.228.221.102 results in a "network hang". So, it would seem that that IPnumber is not publicly reachable. {Assuming the dns entry to be correct] if you're not firewalling it then you need to speak with your provider.Date: Wednesday, January 15, 2020 01:03:27 +0530 From: Padmahas Bn <padmahas@xxxxxxxxx> Hello @Richard and @Monah baki @Richard,-- what is the public IPnumber of your server?I'm not sure whether it's OK or not to tell my public IP openly. But I can give partial IP address. xxx.xxx.221.102-- what is the public DNS name for your server (i.e., the dns entrypadmahasa.ddns.netthat points to the public IPnumber)?Yeah that points to public IP number. @Monah, I think the firewall will not be active by default and I double checked with firewall, which is not active in my Ubuntu system. But should I do any weird thing like, activating it and explicitly allow http traffic in? Until now this is the situation. 1. There is no problem with OS and firewall. 2. There is no problem with web server configuration. 3. There is no problem with my ISP (I had asked my ISP whether they are going to block any incoming traffic but they said No). Still not able to reach my server from internet. Let me know what you guys think the reason could be. Thank you.

One more interesting observation. I've forwarded both both port 80 and port 8080. On port 80 my Apache web server is running on port 8080, Tomcat server is running. When I hit IP_ADDR:80, I got "Connection timed out". When I hit IP_ADDR:8080, I got "This site can't be reached".
