I can't validate the Lightsail cdn SSL certificate and I don't know why?

Question

I cannot validate the Lightsail cdn SSL certificate.

I used this tutorial as base to set the certificates:

`https://lightsail.aws.amazon.com/ls/docs/en_us/articles/verify-tls-ssl-certificate-using-dns-cname-https
`

I followed this procedure.
01- I entered the CDN area, chose the plan and added the origins.

02 - After that I went to Custom Domains.
I created the certificates by generating the keys to be added to the CNAMES.

`

I'm using lighsail's own DNS zone manager.

04 - I go to the lighsail DNS zone and add the CNAMES with name and value.

`

05 - I wait for the validation, which after passing the 72 hours does not activate.

I tried this validation with SSL enabled on the Lightsail CDN and without SSL enabled, but none worked.

I followed the light sai tutorials and couldn't figure out what I'm doing wrong. If anyone has any ideas.

I'm already thanking you for your help.

The only error I see is that for the CNAME entry starting with _4901, you are missing the www in the FQDN. Do a DNS lookup on this CNAME and you would find that it returns a response for FQDN starting with _4901 but without www and no response for the same FQDN with www included

In other words, for the screenshot in 01.png one CNAME returns a response and the other does not. Maybe fixing this would ensure SSL validation

I figured out what's wrong and basically when I was trying to register the domain I forget to copy the `www`.
I was trying like this: `_4901abe5de0d8cf29f6b54b83196fdf0.`

I was trying to register a www domain without the www

but to register the dns I should pass like that: `_4901abe5de0d8cf29f6b54b83196fdf0.www.`

On the CNAME to register as WWW.

that was my mistake.

Thank you for your help.
