Panel Subdomain went Down

[Matthes]

All the sudden my subdomain to my server went down: greyhound.redlinehost.com

It was really out of the blue. Is there anything I need to be checking right now? The panel still responds to the IP it's on, but the subdomain appears to be down.

[Matthes]

My entire server hostname is down. The IP still works. I'm running Ubuntu 8.0.4

Please help.

Just wonder ....have you recently changed the "admin user" of the domain ?

[Matthes]

No, the only thing I did that may have remotely affected it is I did try to add mail.redlinehost.com so that mail would look more formal. However, I don't believe that's what caused it. It has to be something in the hostname/DNS

mh1:~#IS this the correct IP address?

[Matthes]

Sorry for the delayed response. yes, it is.

Then it should work.
Is the ISPConfig server in your LAN? If so, make sure that your ISP doesn't block port 81 and that your router supports loopbacks.

[Matthes]

Actually http://63.147.185.25:81 works but greyhound.redlinehost.com:81 doesn't work. I'm so confused =\

[Matthes]

I started farting around with the DNS in the backend and managed to get it to resolve. =|

Anyway, another question - can I route mail.domain.com everytime I setup a domain too?

can I route mail.domain.com everytime I setup a domain too?

How do you mean that?
