I migrated a Redmine installation from an Ubuntu machine to a Debian one (both 32-bits), and now for some reason, for some users it doesn't return the page but only a 200 OK message. Here is the flow (from Wireshark):

Server: WEBrick/1.3.1 (Ruby/1.8.7/2010-08-16)
Content-Length: 0
As you can see, I get nothing from the server. This is mostly random because this blank page happens sometimes for some users, and for other users it almost never returns the page...
This only happens for issues, any other page I've tested works fine (like listing the issues, creating a new one, etc...).
- RedMine version 2.0.3 with WEBrick
EDIT: Looks like when people use the IP of the RedMine server (192.168.1.5) it works fine. But when using the host name, it doesn't show the issues (only the issues).
EDIT2: Now it shows all pages in blank...
This looks like random... I'm really lost here. Any idea about what can be the cause? Thanks in advance!
