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, 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.
