reconfigure it even not workingi have stopped iptables also not workingand i 
tried above command and got only 110,143 and 25 listen and 80 port is not 
listeningletsecrypt certificate is running in this machine and redirect 443 
port for all the domain websites.All are working except this domain.
if i check in the server itself is working fine but not working outside the 
server.

Have you also made sure the box is listening on the ports in
      question? 

    
    



    
    

Do this command
    

netstat -an | egrep
      '0.0.0.0:25|0.0.0.0:80|0.0.0.0:110|0.0.0.0:143'
    



    
    

You should get this in return if the services are running
      correctly. 

    
    

tcp        0      0 0.0.0.0:110            
      0.0.0.0:*               LISTEN

      tcp        0      0 0.0.0.0:143            
      0.0.0.0:*               LISTEN

      tcp        0      0 0.0.0.0:80             
      0.0.0.0:*               LISTEN

      tcp        0      0 0.0.0.0:25             
      0.0.0.0:*               LISTEN

I'd do a tailored tcpdump on the non-working interface while
        you tried to connect to see if packets are even getting to the
        host.

        Hi Tony,
          

          
          These ip's are pinging and hosting the same server with
            configure multiple network.
          These are working earlier well but suddenly is not
            working this domain reliancehrconsulting.com
          i have stopped iptables also but no luck to respond the
            143 and 25 ports and port 80 for this domain only.
