Can't connect to mail servers from Laravel 6 on Homestead

Question

[Update]

I've tried using wamp on windows and still can't connect to smtp.mailtrap.io

---

I have this homestead.yml config for ports

keys:
  - ~/.ssh/id_rsa

ports:
  - send: 587
    to: 587
  - send: 2525
    to: 2525
    protocol: tcp

folders:
  - map: C:/code
    to: /home/vagrant/code

And this .env config

MAIL_MAILER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=587
MAIL_USERNAME=xxxx
MAIL_PASSWORD=xxxx
MAIL_ENCRYPTION=null
[email protected]
MAIL_FROM_NAME="${APP_NAME}"

But I always get

{"error_code":400,"status":"error","message":"","data":"Connection could not be established with host smtp.mailtrap.io
:stream_socket_client(): unable to connect to smtp.mailtrap.io:587 (Connection timed out)"}

I tried SendGrid too with ports 587 and 2525 but I always get the same message. I tried to connect to mailtrap from ssh

telnet mailtrap.io 587
telnet mailtrap.io 2525

Also tried this from SSH

sudo ufw allow 25/tcp
sudo ufw allow 2525/tcp
sudo ufw allow 587/tcp

But in both cases I don't get any response. I tried to change MAIL_ENCRYPTION to tls but didn't work too.

While starting vagrant I get only these port forwardings

==> homestead: Forwarding ports...
homestead: 80 (guest) => 8000 (host) (adapter 1)
homestead: 443 (guest) => 44300 (host) (adapter 1)
homestead: 3306 (guest) => 33060 (host) (adapter 1)
homestead: 4040 (guest) => 4040 (host) (adapter 1)
homestead: 5432 (guest) => 54320 (host) (adapter 1)
homestead: 8025 (guest) => 8025 (host) (adapter 1)
homestead: 9600 (guest) => 9600 (host) (adapter 1)
homestead: 27017 (guest) => 27017 (host) (adapter 1)
homestead: 22 (guest) => 2222 (host) (adapter 1)

How can I connect successfully to mailtrap from Laravel on Homestead?

Answer 1

I tried using VPN then tried telnet and it worked find and emails got sent so it wasn't any coding or cache issue it was related to connection and closed services or ports solved by using VPN
