Support intro
After the migration of my arm-based nextcloud installation (32 Bit) with php 7.4 to x86 (64 bit) with php 8.1 according to the official documentation the nextcloud log is flooded by “Session ini settings cannot be changed” error messages. All users can use Nextcloud without any problems on client side.
I started the migration with 25.0.13.2 on both sides and upgraded nextcloud on the x86 system in several steps up to 28.0.3 using the nextcloud web gui.
The line numbers beeing mentioned in the error messages are theses:
base.php
=========
[....]
public static function initSession(): void {
$request = Server::get(IRequest::class);
// TODO: Temporary disabled again to solve issues with CalDAV/CardDAV clients like DAVx5 that use cookies
// TODO: See https://github.com/nextcloud/server/issues/37277#issuecomment-1476366147 and the other comments
// TODO: for further information.
// $isDavRequest = strpos($request->getRequestUri(), '/remote.php/dav') === 0 || strpos($request->getRequestUri(), '/remote.php/webdav') === 0;
// if ($request->getHeader('Authorization') !== '' && is_null($request->getCookie('cookie_test')) && $isDavRequest && !isset($_COOKIE['nc_session_id'])) {
// setcookie('cookie_test', 'test', time() + 3600);
// // Do not initialize the session if a request is authenticated directly
// // unless there is a session cookie already sent along
// return;
// }
if ($request->getServerProtocol() === 'https') {
ini_set('session.cookie_secure', 'true'); // < **line 431**
}
// prevents javascript from accessing php session cookies
ini_set('session.cookie_httponly', 'true');
// set the cookie path to the Nextcloud directory
$cookie_path = OC::$WEBROOT ? : '/';
ini_set('session.cookie_path', $cookie_path); // < **line 439**
// Let the session name be changed in the initSession Hook
$sessionName = OC_Util::getInstanceId();

Die Nextcloud instance is behind a nginx reverse proxy.
Nextcloud version (eg, 20.0.5): 28.0.3
Operating system and version (eg, Ubuntu 20.04): Alpine Linux 3.19
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.58-r1
PHP version (eg, 7.4): 8.1
The issue you are facing:
See Nextcloud log below. The issue is indepent from the client and most probably from the version of nextcloud (happend with 27.x, too)
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Install Nextcloud manually according to the official documentation (php packages beeing installed: php81 php81-apache2 php81-common php81-pdo_mysql php81-gd php81-pecl-imagick php81-curl php81-mbstring php81-intl php81-xml php81-zip php81-bcmath php81-gmp php81-session php81-dom php81-xmlreader php81-xmlwriter php81-simplexml php81-opcache php81-sysvsem php81-opcache php-pecl-memcache php81-exif php-pecl-apcu php81-pecl-apcu php81-sodium php81-pcntl)
- Migrate a working arm-based Installation (32 Bit) to this new x86 (64 Bit) installation according to the official documentation
- Use Nextcloud
