Hello

I have an instance of Icinga 2 with Icinga Web 2 running on CentOS 8. All the records and configurations were made through the files in /etc/icinga2/conf.d and others, and everything is working as expected. I am now in the testing phase, an instance on another server, with the same versions I mentioned, but with all the configuration through Director, I already have hosts, host groups and templates, dependencies, etc. I am now having difficulties with notifications, I installed Postfix and have already tested sending successfully through the icinga2 command line, but I am not able to send emails through icinga Web 2.
Can anyone help me with the versions I indicated?

Thanks and good work
