Redirect from non-www version to www. version not working

My website using a custom domain ive obtained over namecheap and set up,is not working the way i want it to.

I have www.growagardencalculator.com/ set as the apex domain and growagardencalculator.com/ set as the redirect,however when trying to access growagardencalculator.com/ im getting SSL errors instead of redirects.
I have a _redirect file set up for growagardencalculator.com/* to redirect to www.growagardencalculator.com/ and i have it set up in netlify domain management/dns settings.

The site works fine im just having issues because of google adsense crawling specifically the non www version and its unable to crawl /ads.txt properly to give me the verification i need to set everything up.

Also ive tried renewing the certificate over 2h ago and this has been going on for over a week i believe

I’ve routed this to our helpdesk, we’ll follow up via email
