SSl certificate not working properly

MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT
Showing this error on firefox and google chrome also. What should I do to fix that

Sounds like you’re using an “origin certificate” - origin certs aren’t browser-trusted are only valid between Cloudflare and your server when using the Cloudflare Proxy, which you can activate by clicking the grey cloud :grey: on a DNS record in the CF dashboard to turn it orange :orange:.
