Could not connect to the SMTP host.

Hi @faarukh,

When you get a chance, could you please share a full error log recorded when you send a test email from WP Mail SMTP > Email Test? Here’s a screenshot for the option to get a full error log. This will give us an idea of what might be going on.

Thanks!

Where I have to send the error log details?

Is there any privacy issue?

Hi @faarukh,

Hi @faarukh,

Thanks for the error details and I apologize for the late response. The error message indicates the issue with the SSL certificate your server is presenting. Please contact your hosting provider and fix your certificate. You may disable the SSL verification using custom code. but it’s compromising your security. In case it helps, here’s tutorial on where and how to add custom codes like that.

I hope this helps!

Ok I will contact them.

Thanks for your help
