Hello Paolo,

I'm afraid that we didn't quite get how the issue look like exactly? Can you explain to us in a little more detail, and send us a couple of screenshots? Or a short one minute video maybe?

Looking forward to your reply.

Hello Paolo,

The 500 Internal Server Error is a server-side error, meaning the problem probably isn't with your computer, Internet connection or plug-ins but instead is a problem with the website's server.

Can you please investigate your server log and see if there is some errors in console and network? And if there are please send a couple of screenshots so that we can take a look.

Also please check once more if the password that you have set up is correct.

Hello Paolo,

That is strange beacuse most people in the world use that port. Can they unblock it?

You can use 465 SSL also but if that doesn't work they need to enable the 587 port.

• SMTP Host – smtp.gmail.com
• SMTP Port – 465
• SMTP Secure – SSL
• SMTP Username – Your Gmail address
• SMTP Password – Your App password (details about setting up an app password can be found in the yellow notice section below)

The most commonly used SMTP Ports are 465 and 587. Port 465 uses “SSL” as SMTP Secure, while port 587 uses “TLS” as SMTP Secure. Make sure to check what the correct SMTP settings are for your mailing provider.

Hope this helps.
