Instead of removing the domain, we just deleted the project. I can see that the site is trying to use the `SSL` that was applied to the project that we deleted. ## Current Behavior - The `www` version has the right `SSL` being applied and works fine. - The root domain issue seems to be that the old `SSL` is being used instead of the new one that should have been generated on March 8 when we added the domain and updated the `DNS` records. - I have updated the `TXT` values to prove ownership, but this error is preventing users from visiting the site. ## Environment - **URL:** [https://gatefold.xyz](https://gatefold.xyz) - **Observation:** Visit `gatefold.xyz` on Safari; it sometimes shows correctly on Chrome but not always. I have come across issues like this in the past and the solution was to remove the `SSL` cert from the server and re-apply, but it doesn't seem like I have control to do that on my end.  system (@system) · 2026-03-10 The domain troubleshooting guide can help with most custom domain configuration issues.

Welcome to the Vercel Community :waving_hand: Could you try the following? * Go to your team’s <[https://vercel.com/[team]/~/domains|Domains](https://vercel.com/%5Bteam%5D/~/domains%7CDomains) page> * Click the *Add Existing* button * Enter `gatefold.xyz` * Follow the verification process Even though you’ve already added TXT records for ownership, you’ll need to complete this flow. It will: * Release the domain from the old deleted project * Clear the cached SSL certificate * Generate a new certificate for your current project This usually resolves within minutes after verification. If you still see issues after an hour, let us know! Byancad (@byancad) · 2026-03-10 Hey @pawlean ! Thanks so much for the response, I added the domains over an hour ago but I am still getting the ssl error. I do see the option to delete the SSL in the SSL certificate section. Should I try that? If so would I be able to generate a new SSL? Byancad (@byancad) · 2026-03-11 Just a quick update, still getting the SSL error and unable to delete the SSL.
