Hello,
I’ve succesfully updated Nextcloud to V21 with PHP7.3 on ISPConfig with php-Fast-cgi. After switching to PHP7.4 I cannot login anymore.
Any suggestion on how to debug?
Thanks!

Please post some entrys from /path/to/nextcloud/data/nextcloud.log

Hello @devnull

Ok, switching to PHP7.4 (CGI/FastCGI), a phpinfo() page shows that’s correctly switched.
If I’m still logged in, I can continue to navigate the Nextcloud page and generate a support-page, which i post here:

I had a Similar issue in the past on another server which was related to permissions to sessions folder of PHP. I’ve tried different ways to solve, but cannot figure out how/where to look this time.

Ideas?

Thanks!

hello, any news or suggestions on how debug?

Beleggrodion · November 8, 2021, 1:56pm

I had the same issue here on my side. Because php 7.3 reaches eol in december this is very annoying. (it’s the only app which still used php 7.3 on the server all other php apps use php7.4 or 8.0)

My Setup looks similar to this from xefil.

Centos 7
Nextcloud 21.0.05, but had this issue already on 20.x some months ago.
Apache 2.4.6
PHP 7.4.25 (cli / php-fpm)

My config file:

<?php
$CONFIG = array (
  'instanceid' => '',
  'passwordsalt' => '',
  'secret' => '',
  'trusted_domains' =>
  array (
    0 => 'cloud.xxx.xx',
  ),
  'datadirectory' => '/www/xxx/cloud.xxx.xx/data/nas',
  'overwrite.cli.url' => 'https://cloud.xxx.xx',
  'dbtype' => 'mysql',
  'version' => '21.0.5.1',
  'dbname' => 'xx_cloud',
  'dbhost' => 'x.x.x.x',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'dbuser' => 'xx_cloud',
  'dbpassword' => '',
  'installed' => true,
  'memcache.local' => '\\OC\\Memcache\\APCu',
  'memcache.distributed' => '\\OC\\Memcache\\Memcached',
  'memcached_servers' =>
  array (
    0 =>
    array (
      0 => 'localhost',
      1 => 11211,
    ),
  ),
  'mail_smtpmode' => 'smtp',
  'mail_smtpauthtype' => 'LOGIN',
  'mail_from_address' => 'xx',
  'mail_domain' => 'xxx.xx',
  'mail_smtphost' => 'x.x.x.x',
  'mail_smtpport' => '25',
  'maintenance' => false,
  'htaccess.RewriteBase' => '/',
  'theme' => '',
  'default_phone_region' => 'CH',
  'loglevel' => 0,
  'app_install_overwrite' =>
  array (
    0 => 'keeweb',
  ),
  'encryption.legacy_format_support' => false,
  'encryption.key_storage_migrated' => false,
  'trashbin_retention_obligation' => '30, 60',
  'mysql.utf8mb4' => true,
  'updater.secret' => '',
);

In the nextcloud.log is nothing which looks like an error (only some IBootstrap depricated warnings of some apps). In the audit.log their is logged an login attempt with an error which looks like someone typed an invalid password (because also the bruteforce db table receive an antry) Also the error.log of apache don’t display anything. First i think perhaps mod_security2.c coul’d be a problem, but after disabling it for nextcloud vhost in apache2 their was nothing changed.

Hello @Beleggrodion ,
I’ve ended updating to php8 and fastcgi (I’m using ISPConfig on a CentOS7) and this allowed me to accomplish the upgrade.
Cheers, Simon
