cannot connect to any sub servers error; took to long to respond

Here is the out put, not sure what virbr0 or where is came from? The router does not have i in the client list. The router list all hosts names, IP address, MAC address and Land and WiFi connections. I beleave I tried once to delete it and I couldn't or it just came back. Something new I saw was isc-dhcp-server, but in trying to delete it the network stopped working altogether so I just disabled it in the boot options. Because of the Dynamic IP it seems to have worked without BIND sine the install and the loacl IP 192.168.0.4 is permanantly leased by the router. The HP x9400 has a dual network card, both active with different MAC address seperated by one number. The intent was for Virtualmin to usr 192.168.0.4 and the other IP for anything else. Both are gigabit/duplex router speed.

any n\more?

here is the out put of "iptables -L -n";

I don't know enough to interperate this info? I also get from "External Connectivity Check"

with the BIND DNS domain feature off and turning it back on I get the message "No virtual servers using the feature BIND DNS domain were found." It was on when I made this post, but now it will not turn back on! Not sure why proxy error as I don't use a proxy and really don't know enough about proxy to mess with it? I do use No-IP to conntect my external IP [174.110.179.31] and the virtual servers are set to a dedicated IP on my cable Modem/Router [192.168.0.4]

My Box is a HP x9400 with 2 NIC's, 2 VGA/DVI outputs, Quad-Core AMD Opteron(tm) Processor 2380 × 8 and 32 GB for real RAM (An HP worksttion with windows workstation replaced by Ubutu-server 14.04.5 and Ubutnu-Gnome destop) I hate windows and the newer ones even more and I format windows and reinstall Linux always. Also take a look at this image uploaded "Screenshot_Virtualmin-Virtual-Servers_2017-10-31.png" Why is my server and sub-servers listed twice? I have looked for symlinks and duplicate directories or files. When I run "Validate Virtual Servers" my sub-servers (listed first) aer there one but nilandtrading.com. (listed last) is there twice, but the result is "All features OK"

Also what is

virbr0  Bridge  192.168.122.1   255.255.255.0> in Network Configuration? it dose not seem to be configured. I just what the Virtual servers to Use eth1[192.168.04] of 2. Don't understand why I would need a bridge? or where it comes from?
 
Anyway I am exasperated and my anxiety is very high now. This all seem to come about on Oct. 24, the first time I used let's encrypt, but there are a buch of things that don't work with it and I will leave this to another time, with questions and how I after a month got it to work (hint it's in the bind recoreds that are missing to use let's encrypt).
