NET::ERR_CERT_COMMON_NAME_INVALID with ZeroSSL certificate!


#1

My domain is: runeproducts.ca

Using Cpanel, had my hosting provider install the a certificate I obtained from ZeroSSL. I am getting this error and hosting provider is unable to figure out the issue. Any suggestions? Cheers!

Hello @HF_Canada

your certificate has only one name - www.runeproducts.ca

So it’s invalid used with runeproducts.ca

Create a new certificate with ZeroSSL with two names: www.runeproducts.ca and runeproducts.ca.

This certificate should work. And a rewrite or other (301) from www.runeproducts.ca to runeproducts.ca

Strange, the CSR I generated was for Requested Extensions:
X509v3 Subject Alternative Name:
DNS:www.runeproducts.ca, DNS:runeproducts.ca

Do I need to generate a new CSR before obtaining another certificate?


#4

I don’t know why your certificate doesn’t contain two names. May be a problem when generating the CSR, maybe a problem of ZeroSSL, which does not support two names.

There are some CSR-Checker (search csr check)

Your certificate starts today and is signed by Letsencrypt.

You did indeed: https://crt.sh/?id=520034366

But after that, you got a certificate for only www: https://crt.sh/?id=520071224

Is it possible you made a mistake somewhere and sent the wrong certificate to cPanel?
