All my domains are showing up as "not secure". How do I change that?

[SKMS]

I just attached a few domains to my website (all of which I purchased through Weebly which is now owned by Square). When I enter each of the domains in a web search, they all show up as "not secure." How do I change this?

I can't expect potential clients to feel confident in my services if the first thing that shows up is "not secure." Help! Thanks.

Welcome to the Community, @SKMS - 

If your domain is hosted at Square, SSL is enabled by default for you the first time you publish your website. Occasionally, it can take 24-48 hours before the SSL certificate is configured.
 

If you have a domain hosted by a third party, you can still have SSL on your website. Make sure your domain name is pointed to the correct IP address and that your website is published. Learn how to connect your domain to Square Online in order to automatically enable SSL.

Have you tried disconnecting & re-connecting the domain? 

Please let me know if this doesn't do the trick for you. I am happy to circle back.
