SMTP - cannot connect to host; error = stream_socket_client

JSilvaR

Hi,

When I try to configure a email, I get the following error:

OSTicket Info:

I tried with port 25, but got the same error...I can connect with telnet from the command line to SMTP server

There is any solution for this issue?

Thanks!!

Are you using self-signed certificate? Why are you using TCP? Can you try type-hinting TLS on the host name (eg. tls://hostname)?

Cheers.

Yes, a let's Encrypt certificate. I have more VM with OsTicket + Let's Encrypt, but this was the first time with that issue.

I tried with "tls://" but got the same error message:

No matter what I do, always show this error with "tcp://". I tried to reboot the entire machine, save the SMTP server info and then introduce the user/password, but didnt work...

It may be due to self signed certificate. Please try these changes out:

If that doesn’t work you’ll have to look at the server logs and mail server logs for any related errors.

Cheers.

So that error looks like its saying permission denied. Are you running any kind of firewall that might be preventing the connection?
