"Send Invitation" doesn't send any emails, invoice sending works fine


I have a problem with new user registration. I can add user by “Add user” form, but system doesn’t send email with invitation and access data. Invoice sending works fine.

I will be very grateful for any help.

I forgot say very important information, I have self hosted version on Debian VPS with Nginx

I’m not sure… are there any errors in storage/logs/laravel-error.log

Also, can you check your email logs to see if the email was sent but not delivered.
