[Bug] Invite mail doesn't reach the addressee

[DrilealoTatarara]

Describe the bug Invite mail doesn't reach the addressee when trying to invite a member to the space. I've deployed a self-hosted Appflowy Cloud, and worked correctly. All is configured to be reacheable from the local network. Ir works well when changing cloud method to self-hosted cloud, and modifying the base URL. Problem comes when i try to invite someone. It doesn't return any error, appears the confirmation message that tells that invitation was sent successfully, but when go to check it to the mail, isn't there. I've been checking the logs of the docker compose, and the output is normal, no errors, just telling that the addressee is already invited (i did several tries). Here is the terminal output:
