Greetings,
Thank you for asking.
I am sorry to hear this.
Currently, I receive a different one, 521 error as follows:
Before moving to Cloudflare, was your Website working over HTTPS connection?
You could determine this by:
- Use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com .
- The link is in the lower right corner of that page.
- Give it five minutes to take effect, then make sure site is working as expected with HTTPS without any error
- Check with your hosting provider / cPanel AutoSSL and renew it
- Only then, when your website responds over HTTPS, you should un-pause Cloudflare and double-check your SSL/TLS setting to make sure it’s Full (Strict).
May I ask if and what steps for troubleshooting 525 error have you tried from the below post already?
