Error uploading file "<>": Token Expired. Please reload page

Owncloud 9.1.5 (EPEL) on CentOS 7-current, using PHP 7.1.6 (from the remi-safe repos) with MySQL.

Users are trying to upload a large amount of data. Uploads abort with the above message after varying periods of time and data uploaded.

I don't see any recent posts in the Google referencing this message, so I assume I have done something wrong rather than having discovered a fault in Owncloud, so I don't think submitting a bug report is necessary yet.

Does anyone have any ideas what I'm doing wrong?

try to modify the value of

session.gc_maxlifetime

in

/etc/php/7.0/apache2/php.ini

it's set to 1440 which is 24 minutes

if your upload takes longer, maybe adjust the value.

let me know if it helps.
