If your website shows an error related to the SSL version or cipher mismatch and you are using Cloudflare, follow these steps to fix it:
Step 1 - Reset Universal SSL
Log in to your Cloudflare account at Cloudflare.com and disable Universal SSL:
After disabling it, wait a few minutes for changes to take effect, then enable Universal SSL again.
Step 2 - Clear the Cloudflare Cache
Now, to make sure that you are getting the latest version of your website, purge the Cloudflare cache.
Once it's done, give it a few minutes, and your site should be back up and working 😊
