I created Origin Certificate in cloudflare and installed on my Apache on Debian VPS using the guide https://support.cloudflare.com/hc/en-us/articles/217472077.
My URL is like this: https://socket.mydomain.com/
I am getting warning "There are issues with the site's certificate chain (net::ERR_CERT_AUTHORITY_INVALID)." whenever I visit above URL, why? Remember that I am not using old versions of browsers. Tell me what I am doing wrong?
