your session is invalid or expired [SOLVED]

[chris972]

Solution at the end

Hi,

On my server I have Postfix + Dovecot + Roundcube.
I don't use rouncube much, it's mainly as a backup in case my other means of access to mail are cut off.
Yesterday I realized that I couldn't connect to it.
I immediately thought that there was probably an update that would be useful to install. So I went from 1.5.2 to 1.6.3 (under Gentoo)
But the problem persists.
A priori, Dovecot is not the cause, since I always manage to connect to it by other means (evolution, mail under Android) whether by imap, imaps, pop or pops.

I can't determine if this is caused by roundcube or a php/apache configuration fault. php could very well be the cause since I probably didn't test roundcube after the last php updates. A problem with sessions ?

When I enter my username in roundcube, I get a red message: "your session is invalid or expired" and I stay on the login page.

I tried several configuration changes, especially imap_auth_type without any results.

I don't know what to test.
Thank you in advance for any help you can give me.

Edit:
I had completely forgotten that in order to secure my server, I had followed some recommendations without understanding everything, one of which was to add instructions to the header in the Apache virtualhost configuration:

Code: [Select]

                 Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure
                 Header always append X-Frame-Options SAMEORIGIN
                 Header set X-XSS-Protection "1; mode=block"
                 Header set X-Content-Type-Options nosniffAnd by deleting the first line (edit Set-Cookie), the problem disappears.
Sorry for the unnecessary noise.
