I’m designer not smart with those problem, I will grateful if you guys can help. I got a problem with my site. I tried https:// which is fine, but when www. is error 521… what should I do with this? Is it Cloudflare or my bootstrap setting? Or domain company?
The www version is a separate website from the non-www. You will need to set up a redirect in Cloudflare. If the suggestions in our FAQ don’t work, you will need to contact Cloudflare’s support - Contact us
