What is the error when running owncloud + roundcube?

Question

Nginx

Good afternoon! There is a server on centos 7. It has nginx (1.6.3) + php-fpm (5.5.30). This is all about owncloud 8.2. We decided to screw roundcube there. After dancing with the settings, it turned out to enter the RC, but if you immediately press F5, the following error will fall out:

You don't have any email account configured correctly yet. Please check you username and password.
You can manage your email accounts here: Settings
ERROR: Technical problem, Unable to login to roundcube

Then if you go to the "Personal" settings and enter the data for authorization in the RC there, then after clicking "save" the status hangs "saving" and that's it? and indeed it always hangs, but the data gets into the database.
This is what the owncloud log says

OC_RoundCube_App.class.php->refresh(): Failed to refresh the RC session.

Does anyone have experience with this problem? I'll try to replace nginx with apache and see what happens

Answer 1

The problem remained open, I had to move to apache.

Answer 2

See server logs.
