Not receiving mails from forum

Hi everyone

I have been setting up discourse with mailgun, and followed this youtube video from Paul Nicholson. https://www.youtube.com/watch?v=vAPuHBlcOms&t=441s

My forum works as it should, and have been for weeks. It was first today when i tried to recreate my password by email, that i realized that i dont receiving the emails.

I hope someone can help me to get my mails working

Thanks from Denmark

I may have found the reason. Cant delete topic. Will write solution when im sure
