Laravel SMTP mailtrap [Connection timed out #110]

Question

I'm trying to send email with Laravel using mailtrap for testing in a local homestead server.

The firewall shows no rules blocking port 2525.

Mail driver config:

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=$USERNAME
MAIL_PASSWORD=$PASSWORD
MAIL_ENCRYPTION=null

Error returned:

Fatal error: Uncaught exception 'Swift_TransportException' with message 'Connection could not be established with host mailtrap.io [Connection timed out #110]'

Answer 1

Your hostname is invalid. It should be smtp.mailtrap.io. More info here: https://mailtrap.io/blog/2018-03-09-why-mailtrap-updated-its-smtp-host

P.S. Mailtrap doesn't have static IP addresses, so your way with IPv4 will work not so long amount of time.

Answer 2

Adding to Alexey Vasiliev answer , after you fix the hostname don't forget to clear the cache using the following commands

php artisan config:clear 
php artisan cache:clear
