Warning the sites url settings do not match the host set in local

I have no idea why this message is suddenly popping up… any help will be much appreciated.

I’m getting this as well for a specific site installation. Also, when I click the “Fix It” button, it prepends the URL for the site to every reference to http:// within the database which then causes it to break again. For example, if the Site Domain is “mytestsite.local” and I run the Fix It command, the siteurl option in the DB becomes https://mytestsite.localmytestsite.local

Then every time after that it continues to prepend that URL to all URL references within the DB. This just started happening this morning.
