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 entry >> > padmahasa.ddns.net > >> that 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.
