Task assignee e-mail notification error

Bug
1

Hello, we successfully completed a K8S setup using the values ​​YAML file below. Almost every function works without problems, but when we enter the SMTP settings, although we can send test mail and some other emails, we get an error like the one below when assigning a task. When we send test mail from the CLI or add someone to the team, emails are sent without any problems, but when we assign a task, it cannot connect to the SMTP server. Thinking that maybe it’s not receiving the settings, we also provided the SMTP settings in the config.yml file in addition to the environment file, but it didn’t work. Has anyone encountered this situation before?
