NET::ERR_CERT_COMMON_NAME_INVALID error is showing up on Chrome

My website was working fine for 1-2 days after activating the Cloudflare full ssl. But after that the error started to showing up NET::ERR_CERT_COMMON_NAME_INVALID. Please help me what should I do now?

What is the url of your site?

Hi @anshulk045, as @Jake1st commented, can you share the domain? That’ll help troubleshoot. In the meantime, this Community Tip has some detail and quick fix suggestions, https://community.Cloudflare.com/t/community-tip-fixing-net-err-cert-common-name-invalid/48326. As it was working and is not now, I’d suspect a certificate on your origin is expired/removed and ssl on your SSL/TLS app is set to expect it (i.e., Full (strict)). Post back and let us know how it works out.
