Dashboard widget recommendations took XX.XX seconds to load

Hello.
A cordial greeting to everybody.
I have installed NextCloud on an Ubuntu VM on GCP as a container. The page loads fine, however a few minutes after browsing it, it starts to take a long time to load any requested page. Looking at the logs, I see the following repeatedly:

Error no app in context Dashboard widget recommendations took 45.11 seconds to load. 2022-08-22T10:30:26-0500
Error no app in context Dashboard widget recommendations took 45.15 seconds to load. 2022-08-22T10:24:38-0500
Error no app in context Dashboard widget recommendations took 45.04 seconds to load. 2022-08-22T10:17:35-0500
Error no app in context Dashboard widget recommendations took 30.13 seconds to load. 2022-08-19T16:18:48-0500

Slow loading is always present.

The versions are the following:
Next Cloud 20.0.0
Ubuntu 22.04.1 LTS
Apache 2

The config.php is:

<?php $CONFIG = array ( 'htaccess.RewriteBase' => '/', 'memcache.local' => '\\OC\\Memcache\\APCu', 'apps_paths' => array ( 0 => array ( 'path' => '/var/www/html/apps', 'url' => '/apps', 'writable' => false, ), 1 => array ( 'path' => '/var/www/html/custom_apps', 'url' => '/custom_apps', 'writable' => true, ), ), 'memcache.distributed' => '\\OC\\Memcache\\Redis', 'memcache.locking' => '\\OC\\Memcache\\Redis', 'redis' => array ( 'host' => 'redis', 'password' => 'lifebox', 'port' => 6379, ), 'instanceid' => 'occ5xxxxxxx', 'passwordsalt' => '76kxxxxxxxxxxxxxxxxxxxxxxx', 'secret' => 'lQ/Uxxxxxxxxxxxxxx', 'trusted_domains' => array ( 0 => 'localhost:9123', 1 => 'xxxxxxxxxxxxxxxxxxx.com', 2 => 'xxxxxxxxxxxxxxxxxxxxxx.com', 3 => 'xxxxxxxxxxxxxxx.com', ), 'datadirectory' => '/var/www/html/data', 'dbtype' => 'mysql', 'version' => '20.0.0.9', 'overwrite.cli.url' => 'http://localhost:9123', 'dbname' => 'nextcloud', 'dbhost' => 'db', 'dbport' => '', 'dbtableprefix' => 'oc_', 'mysql.utf8mb4' => true, 'dbuser' => 'nextcloud', 'dbpassword' => 'xxxxxxx', 'installed' => true, 'skeletondirectory' => '/xxxxxx-skeleton/', 'updater.secret' => '$2yxxxxxxxxxxxxxxxxxxxxx', Has anyone experienced the same error or know how I can make the page not take so long to load? Thank you so much.
