Can't set up SMTP

Trying to set up our email smtp. We use a GSuite gmail with our own address, such as hello@ourcompany.com

Have tried all ports and all combinations of host name configurations but keep getting:

On 465
Failure sending message - Unable to read data from the transport connection: net_io_connectionclosed

or

On 25 or 587
The SMTP server requires a secure connection or the client was not authenticates. The server response was: 5.7.0 Authentication Required. Learn more at

Should I be authenticating in our Gmail or Google Admin console? TIA

Hi,
You may have to use a app password
