Universal SSL is essential for your website to work with HTTPS when you don’t have a valid SSL certificate yet. In the majority of cases, it’s recommended to keep Universal SSL enabled. However, sometimes you need to temporarily disable Universal SSL to solve website issues.
If you have enabled Cloudflare for your domain, you can manage SSL from the Cloudflare Dashboard:
Log in to your Cloudflare Dashboard, and click on the domain in question. Then in the left menu, choose SSL/TLS → Edge Certificates:
Scroll down to the Disable Universal SSL section and click on Disable Universal SSL:
To enable it, just wait for a minute and then click on Enable Universal SSL:
That's it! Your Universal SSL should be working correctly 😊
