Error: enable cookies, cloudflare apps

i am trying to use one of the apps provided by Cloudflare. and i am recieving a message saying i need to enable cookies. please help.

May I ask if you are using Mozila Firefox? :thinking:
How about TOR Web browser or some other add-on/extension if any, or maybe anti-virus software running at your device?

May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?

Before moving to Cloudflare, was your Website working over HTTPS connection?
Before doing anything at Cloudfalre settings, you could determine if you have a valid SSL certificate installed at the origin host/server by your web hosting provider or your own VPS/dedicated server following the steps from below:

  1. Use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com .
  2. The link is in the lower right corner of that page.
  3. Give it five minutes to take effect, then make sure site is working as expected with HTTPS.
  4. Check with your hosting provider / cPanel AutoSSL / ACME.sh / Certbot / Let’s Encrypt or some other and renew it accordingly.
  5. Only then should you un-pause Cloudflare and double-check your SSL/TLS setting to make sure it’s Full (Strict).
