Can't login with roundcube is using cloudflare [solved]

[bagu]

Hello,

I see a similar post, but it's not really the same situation.

I use cloudflare, only as DNS for my host mail.bagu.fr
But, if i try to log in roundcube 0.9.5, i receive an apache error 500

If i switch to gandi DNS : no problem.

I've try to login with the entire mail (and %h in main.inc.php) but no success.
Do you have an idea ?

What shows up in the RoundCube error log?

[bagu]

Nothing, the error log is empty


The only error i get is in apache :


[Tue Dec 03 12:11:31.839481 2013] [core:error] [pid 1764:tid 1416] [client 88.184.248.105:1981] End of script output before headers: index.php, referer: http://mail.bagu.fr/

Error message here too... using Firefox. All other websites/emails are working fine.

With firefox, i can see that the POST request for login fail.
I there something wrong to use roundcube and this free CDN ?

Have you tried using the IP address of the mail server in the RoundCube config file?

[bagu]

If you talk about

$rcmail_config['default_host'] = '%d';

I'v try :

$rcmail_config['default_host'] = 127.0.0.1;

(mail server is on the same system), but i get an error in php log.


EDIT :
Ok, it seem it work with :

$rcmail_config['default_host'] = '127.0.0.1';
