How do I renew my websites security certificate?

[emmyone]

when I try to access my website it says site not secure and the advanced options tell me that the hosts security certificate expired 4 days ago. What can i do to fix this seemingly because I can't get help anywhere else.

Hi emmyone,

Just a generic thought as we don't have any details other than "your website".   For starters, who's hosting your site?   Is this a separate site that you have?   Are you then linking to Square's online site for sales or is your website just through Square?  For example, we have a site that is separate from Square's free online site.  Our site host handles the "https" listing and provides the security certificate - this is all included with our yearly fees.  We then have a link to Square's free online site for online shopping, they (Square/Weebly) handle the "https" and associated security settings.

Weebly is my host, my domain is through google domains. Square is linked.
