Browser Component - TLS settings

Dear all, 

does anyone know how to access a site using TLS 1.1 or higher via the 

SOAP UI Browser Component?

I'm facing the error 'When logging in, be sure to use a secure HTTPS connection with TLS 1.1 or higher. If you still can't log in, ask your Salesforce admin for help.' when trying to authenticate at Salesforce.

This issue happens while trying to get an Access Token for an oAuth connection.

Thanks in advance!

Mo
