Today I noticed my website http://mint-nachhilfe.ch/ was down, but other people (located in different networks) said it looks up from there. When I came home, I double-checked, and I can really reach it from here. Also, this website considers it down.
- It's a Tomcat webapp, connected to an Apache2 server. I restarted both, no change.
- Another (ruby on rails) application is connected to this Apache2, which I couldn't reach either, but is considered online by above check website.
- At any point, I could directly connect to the Tomcat over http://mint-nachhilfe.ch:8080!
I don't know how to go on searching for the root error. I assume it's related to the Apache2 server, but how could that be?
It is reachable directly by the IP
22.214.171.124 I got from an
nslookup triggered inside the problematic network. The problem seems to be related to Apache's domain distinction. My VirutualHost entry looks as follows (there are few others as well):
<VirtualHost *:80> ServerName www.mint-nachhilfe.ch ServerAlias mint-nachhilfe.ch *.mint-nachhilfe.ch JkMount /* worker1 </VirtualHost>
Is there anything wrong here?
