Application Configuration

Optimize scripts enabled. Previews enabled. ClamAV, Collabora and Push Notify enabled. UserData mounted via HostPath (not shared with SMB.) Ingress with domain name (traefik) enabled, TLS via clusterissuer.

The rest are defaults, except for the mandatory passwords.

Describe the bug

The installation was done using the migration guide on truecharts.org.

When trying to send a test email in the administration settings for nextcloud, I get a response saying "A problem occurred while sending the email. Please revise your settings."

This is probably not relevant due to the following appearing in "occ log:tail":

Error     PHP                 Trying to access array offset on value of type bool at /var/www/html/apps/settings/lib/Settings/Admin/Server.php#76      2023-06-26T15:57:51+02:00

To Reproduce

Install according to application configuration Configure SMTP email Try sending test email

Expected Behavior

Email get sent

Additional Context

None

I've read and agree with the following

• [X] I've checked all open and closed issues and my issue is not there.

I've verified that this issue is the same on a freshly installed nextcloud, without migration (only ClamAV and ingress set)

I also see now that the error message I am getting is only related to the cron job section. Either way, I'm unable to see anything in any logs about what is going wrong. My SMTP server is not getting a connection, and it works from other apps.

So I was able to figure this out at last:

I was using protonmail-bridge chart and new versions of Nextcloud will try STARTTLS automatically. This caused it to fail to validate the TLS certificate. Issue is that there is no error message displayed anywhere in any log I could find. So not an issue with truecharts, but maybe not getting any useful logs anywhere is? Don't know...

Solution was to add the following to config.php and then restart the chart:

"'mail_smtpstreamoptions' => array( 'ssl' => array( 'allow_self_signed' => true, 'verify_peer' => false, 'verify_peer_name' => false ) ),"
