SMTP ERROR: Failed to connect to server

Hello,

Lately I have not been able to send emails using SMPT.
I’m using gmail (a GSuite account), wich untill now, have never been a problem.

When I use the Knews test it shows this output:

“SMTP ERROR: Failed to connect to server: Connection timed out (110)
SMTP connect() failed.

https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

Error al enviar.”

I’ve tried everything form the PHPMailer troubleshoot guide.
DNS with gmail is working properly, openssl is loaded and the conexión from my servers console to gmail works (I’ve tried ping and telnet, both succesfully).

Could you give me some guidance please?

Thanks a lot!
