I have to support a Nextcloud environment which was implemented and maintained (so far) by someone else. Moreover I’m nearly completely new to Nextcloud… .
Nextcloud 21.0.4 (running on CentOS 7 (64-bit))
<?php $CONFIG = array ( 'instanceid' => '***********', 'passwordsalt' => '***********', 'secret' => '***********', 'has_internet_connection' => false, 'simpleSignUpLink.shown' => false, 'trusted_domains' => array ( 0 => 'DNSname', 1 => 'Hostname', 2 => 'IP', ), 'skeletondirectory' => '/NextData/data/skeleton', 'share_folder' => '/Shares', 'auth.bruteforce.protection.enabled' => false, 'debug' => false, 'datadirectory' => '/NextData/data', 'dbtype' => 'mysql', 'version' => '126.96.36.199', 'overwrite.cli.url' => 'http://DNSname', 'overwriteprotocol' => 'https', 'dbname' => 'nextcloud', 'dbhost' => 'localhost', 'dbport' => '', 'dbtableprefix' => 'oc_', 'dbuser' => '***********', 'dbpassword' => '***********', 'installed' => true, 'memcache.distributed' => '\\OC\\Memcache\\Redis', 'memcache.locking' => '\\OC\\Memcache\\Redis', 'memcache.local' => '\\OC\\Memcache\\APCu', 'redis' => array ( 'host' => 'localhost', 'port' => ***********, ), 'ldapIgnoreNamingRules' => false, 'ldapProviderFactory' => 'OCA\\User_LDAP\\LDAPProviderFactory', 'mail_smtpmode' => 'smtp', 'mail_sendmailmode' => 'smtp', 'theme' => '', 'loglevel' => 2, 'maintenance' => false, 'mysql.utf8mb4' => true, 'twofactor_enforced' => 'true', 'twofactor_enforced_groups' => array ( 0 => 'admin', ), 'twofactor_enforced_excluded_groups' => array ( ), 'mail_from_address' => '***********', 'mail_domain' => '***********', 'mail_smtphost' => 'our mail relay', 'mail_smtpport' => '25', 'updater.release.channel' => 'stable', 'default_phone_region' => 'DE', );
The test mail, which can be triggered in “Administration > Basic settings > Email server”, works flawlessly! I receive the test message immediately. However notification mails (if someone uploads a file or changes a file) aren’t sent. On our mail relay I only see the triggered test mails but no notification mails at all. So it looks like that these notification mails aren’t triggered.
Maybe some kind of mechanism, which checks for changes (and therefore triggers notification mails) doesn’t work?
At some point of time the notification mails stopped working. As I wasn’t responsible for the system back then, I cannot say if something was changed. The only thing I know: this issue exists for at least 3 months. I saw that there was a fix for notifications in 21.0.4. Therefore we upgraded our Nextcloud server from 21.0.2 to 21.0.4. Unfortunately it didn’t get fixed.
Does anybody know what/where to check?
Is there any specific log regarding “notifications” which we can analyze for errors?
Thank you very much!
