Erro 500: Could not open socket: stream_socket_client(): (Connection refused)

[fcm.moura]

Hello,
When setting up the email service and trying to send a test message, the following error appears:
Erro 500: Could not open socket: stream_socket_client(): unable to connect tcp://mail.pascoalmoretti.com.br:587 (Connection refused)

For other applications on the same server I have no problems, only for ESPOCRM
Do you know how to inform me if I need to configure a file or something?
Sorry English, I'm using google translator

This should NOT be in bug reports section.

[esforim]

I see it is port 587 (Porta). Maybe try Port 465 as your email might be SSL, or temporary do a test with Port 25

[fcm.moura]

Do I need to configure any internal files on the server?

[Maximus]

No, I think he is talking about changing your SMTP configs in EspoCRM. Change Security to 'SSL' and Port to '465' and try to compose an email or send the test email.

[esforim]

Yes, have a look at Seguranca and Porta in your screenshot. Try change that, then send an email see if you can send email.

[fcm.moura]

the same message occurs for both port 465 and port 25. I suspect it is something of the application. Other tools I use at the provider, I use the same settings and this error does not occur.

[esforim]

I did a quick search and this error is related to PHP. Have a look at your PHP extension, try see if there a Zend option? Or try changing your PHP Version.

Or could ask your Host support to see know how to fix "Could not open socket: stream_socket_client()" error.

Have you tried any other email yet? Try using more common public email for testing first (e.g. Hotmail, Live, Outlook, Gmail, Yahoo, etc)

[fcm.moura]

Hi,
I've tried everything, changed ports, changed emails, private and public, but I hadn't tried this PHP option. I'll check

[fcm.moura]

Hello, I managed to solve the problem by replacing the SMTP address (mail.mydomain.com.br) with LOCALHOST. That is, instead of putting the full address, I just put localhost and it worked.

[esforim]

That a smart work-around.

[criffoh]

I had the same problem and the solution was to open the outbound port (993) in the server that hosts EspoCRM
