Stuck SSL state preventing provisioning / certificate parameter required

Hello Netlify Support Team, I hope you are doing well today. I am creating this post because I am completely stuck trying to generate a Let’s Encrypt SSL certificate for my custom domain.

Whenever I click the provision button, I receive this exact error: “certificate parameter is required when updating an existing certificate”

Here are my project details:

  • Site Name: kessociety.netlify.app

  • Custom Domain: karthikeyaeducationalsociety.com

My DNS changes have fully propagated (the site loads over standard HTTP), and the Netlify UI shows the green checkmarks for DNS verification. From reading previous forum posts, it seems like I might have a “stale” certificate state stuck on your backend that is blocking the automated process.

Could a support engineer please manually clear or reset the SSL state for my site so I can generate a new certificate?

Thank you so much for your time and help!
