I've just completed my DA installation on Centos.
Everything seems to work fine however, when trying to access PHPMyAdmin it goes to: http://IPSERVER/phpmyadmin
This comes with an error page:
Code:
Bad Request

Your browser sent a request that this server could not understand.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

When i access PHPMyAdmin through the domain name: http://DOMAIN.COM/phpmyadmin everything seems to work fine.

The same problem occurs for Squirrelmail and Roundcube
Is there anyone who knows what could be wrong?

Thanks..

EDIT:

I found this in the error log (i 'X'-ed out the ip address with the hostname section):

Code:
ModSecurity: Access denied with code 400 (phase 2). Pattern match "^[\\d\\.]+$" at REQUEST_HEADERS:Host. [file "/etc/modsecurity2/optional_rules/modsecurity_crs_21_protocol_anomalies.conf"] [line "60"] [id "960017"] [msg "Host header is a numeric IP address"] [severity "CRITICAL"] [tag "PROTOCOL_VIOLATION/IP_HOST"] [hostname "X.X.X.X"] [uri "/phpmyadmin"] [unique_id "S5bAKlGrU0EAADi0HfEAAAAA"]

EDIT: Appears the ModSecurity setting was rejecting the connections..

CASE CLOSED
