Help me NET::ERR_CERT_AUTHORITY_INVALID CloudFlare Origin Certificate

Hello everyone
First apologize if my english is bad.
I used CloudFlare to install ssl for my website.
But I don’t understand why there are times when I get an error
NET :: ERR_CERT_AUTHORITY_INVALID CloudFlare Origin Certificate
When I visit my website, sometimes I won’t get it even if I clear the cache. On another computer, this doesn’t happen.
People let me ask why that is and does it matter.
If possible, how to fix it
Thanks everyone

Hi @khanhvq04890, some suggestion in this #CommunityTip, Community Tip - Fixing NET::ERR_CERT_AUTHORITY_INVALID. It may just be a propagation issue if this is a recent setup. What is the domain?

my domain anime81.com


I get the error as the image above
Thank you for helping me


about 5-10 minutes after I try to re-page f5
I can get in.
But this error has occurred since I registered the ssl up to now, 6-7 hours.

Are you only seeing the issue in opera? Looks great in Chrome:

I have the above problem in every browser but it doesn’t always happen. in about 1 hour it will happen and some time it will work again automatically
