Hello axelerao,
Chances are that port 80 or 443 is closed/blocked by a firewall. It can come from either your firewall or the remote one.
Try reproducing the issue from a different network.
- If it does work fine, do a traceroute and note it down. Then, do a traceroute from your network and see what is the last host response >> The problem won't be coming from that host - it will comes from the one following it (usually the web hosting server).
- If it doesn't work either, you'll have to contact the network/system administrator and request support regarding the firewall's blacklist on port 80/443
Best,

Hello,
**First, make sure that your IP is not blacklisted on the remote firewall**
It would also be possible to add the website to your DNS server (on your Zentyal server)
Simply add those 2 entries to it:
Domain: bnv.com.do
IP address: 201.229.188.194
Domain: www.bnv.com.do
IP address: 201.229.188.194
and that should solve it.

and that should solve it.
Perhaps as a workaround... but:
1 - "managing" domain you don't own is not best practice
2 - to me (sorry if it looks like nitpicking :-[, it's really not the aim) www.bnv.com.do is not a domain but hostname (FQDN to be more accurate)
Your point about potential blacklist is a good one ;-)

I do concure - still, this is the terminology used in Zentyal. Using a more "proper" way of naming this would just confuse some administrators.
Bottom line, if Zentyal would name this "apple and orange", well, I would say:
apple and orange: bnv.com.do
Your point about potential blacklist is a good one
This is probably the most common problem that a lot of network administrators are facing. That is why the traceroute requested earlier.
More over, axelerao, you should do a ping to the remote server using Zentyal itself and not form your client (desktop).
