Privacy error popping up when I click i try to enter jy website from my google business page

[thaisleal]

So for a few days now every time i try to click on my website i continuously get the following message:

"Your connection is not private

Attackers might be trying to steal your information from www.thais-leal.square.site (for example, passwords, messages, or credit cards). Learn more

NET::ERR_CERT_COMMON_NAME_INVALID"

This message is only coming up when I navigate from my google page. when i write it out directly in the url that message does not come up! How can this be fixed?

HI, when you type the URL just type thais-leal.square.site, no www is needed.
