How can I solve "Connection could not be established with host smtp.gmail.com"?

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=secret
MAIL_ENCRYPTION=tls

this one is right config values.. are you using 2 step verification for that email?

if its you have use app password or normal password is fine...

@biishmar Like description in my question above. I had try it all, but it's the same. It does not work. In my localhost it works. But in my staging server, it does not works

Have you removed .env from the gitignore. If not, then make the necessary changes in the .env file to the server and run php artisan config:cache.

I think this may help you.

@VijayKadiyam No. I don't remove it. I had run it. But it's the same

Have you removed .env from the gitignore.

Don't do this unless you want all your confidential settings stored in your repository ... not a good idea.

@Snapey I don't remove it. Then what is the right solution to solve my problem? I still have not found a solution

Use Mailgun, Amazon SES, or some other sending service. Your server's IP may have been associated with spam in the past and be blocked by Gmail.

@Snapey In my localhost, it works. This just does not work on the staging server.

@sutherland I am still confused. Because when I try on my localhost, it works. This just does not work when run the send mail on the staging server

Have you checked to make sure port 587 isn't blocked for outgoing traffic on your staging server?

@Defrag How can I check it?

@moses that's because your local IP address is different than your server's IP. Your home IP is unlikely to get flagged by Gmail for spam, but you never know what your server's IP was previously used for.

@moses - do you have access to the command line on your staging server? If so you can try

telnet smtp.gmail.com 587

If you don't get a connection refused error then the issue is not network related

Where is the staging server? I know for me, SMTP through Gmail doesn't work from my Homestead environment when on Verizon FiOS. I believe they are blocking that port.

One other thing to check is to make sure if you're setting any parameters in your .env file that are multiple words (such as a sender name) that you put them in quotes. i.e.

MAIL_FROM_NAME=First Last

will cause an error. Instead use:

MAIL_FROM_NAME="First Last"

It may not be your problem, but I've been burned on it before.

i am facing same issue still not resolve.

when i change my mail_driver to sendmail it gives me this error proc_open() has been disabled for security reasons

@MUZAMMILRAFAY - Your ability fix this will depend on where your hosting your application and what access you have to configure php.

Have a look at the possible solutions at

I am suffering from the same issue as @moses - Laravel Mailing works on my local host but not when the project is hosted on GoDaddy - any answers please?

Hello @moses does your issue resolved or not?

Same issue here, no solution yet?

Hi Guys, did you change your .env files on your servers? Otherwise it will not work. Your .env file should not been pushed to your Github or other server so.

When deploying on laravel forge, you can change your env file on the admin page, when using ftp, you should change your configuration when uploading it to the server.

When you use gmail with 2 factor authentication, you need to create an app specific password.

Hopefully it gives an idea.

Considering all the SMTP credentials are correct and properly configured, the reason why it works on localhost and not on staging server might be becasue of SELinux being enforced in the server.....

checkout if the SELinux is enforced. If it is,

$ setsebool -P httpd_can_network_connect on

$ setsebool -P httpd_can_sendmail on

I think this maybe something to do with IPv6 I just upgraded my server from 32bit to 64 bit (and changed to ipv6) and am now getting the error.

If you are using Amazon EC2, do ensure to set outbound rules for SMTP (25) and SMTPS (465) to Anywhere.

MAIL_MAILER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=465
[email protected]
MAIL_PASSWORD='yourgmailpassword'
MAIL_ENCRYPTION=ssl
[email protected]
MAIL_FROM_NAME="${APP_NAME}"

Tried Now, Just change your Port to 465. You are set

@moses when you use gmail as your outgoing mail server you need to disable 2 step verification in your gmail account try this hope it will works fine... ;)

@jeevamugunthan hopefully moses has not been waiting 2 years for your answer

@snapey haahaa...!! i didn't see the posted date , but the conversation is still going on i mention the wrong person
