Mailgun api problem, work local, not on server

Hi! Anyone used mailgun/bogardo with forge/digitalocean to send email ? I'm having a hard time!! Everything is working fine on locahost, email are sent. Server, nothing, no error, code after the Mailgun call work! I have tried hundreds of combination in the last two days of .env, mail.php, mailgun.php, service.php and nothing. From the server I'm able to curl the mailgun api and send a test email. Composer.json is the same, did composer install, composer update. If anyone has a idea or seen this before would be appreciate :) I'M also using Spark
