After transferring a domain from another registrar to AWS, I can't get it verified in the Certificate Manager. I created a hosted zone, the CNAME records created by the Certificate Manager are there, I tried with the DNS tester - the records seem good. However it still says "pending validation". I tried a few times, waited a couple of days and it doesn't seem it will work.
I'm totally out of ideas, any help?
DNS validation require 2 things to be setup correctly. Record Name and Record Value
Check if you're correctly setting these in Route53. Reference Doc here: https://docs.aws.amazon.com/acm/latest/userguide/dns-validation.html
Now 2 issues which are very common
In the Record Name part confirm that you're not adding your domain name in the value. _X is the only part you have to copy-paste. If you copy _X.YourDomain then 'YourDomain' part is duplicated
Record Value ends with . (a period / dot). Don't remove that period
You can verify the settings from https://mxtoolbox.com/ it has various configurations like A record, CNAME, DNS Validation, etc.
I have one question to define the dns records. In this url (https://cloud.google.com/dns/docs/records), I read
Note: Adding the # symbol in this field causes the record to fail.
This generates some doubts, until now whenever I had defined the records in Google Cloud DNS, instead of using # I left it empty (thus referring to $ ORIGIN)
This is so?
that is, for example
example.com. 300 IN TXT "v = spf1 xxxxxxxxxxxxxxxxxxxxxxxxx"
example.com. 300 IN MX 10 server.domain.com.
Thank you very much
In the image are my current Hosted zone details on AWS. When I visit www.giftforhilt.com it works but when I visit giftforhilt.com it does not work.
How can I fix this?
Can you add another A record using the record name giftforhit.com, the same way that you have done for www.giftforhit.com. just now use without www. And one thing is better when you give the ttl(time to leave) 60 where you did 3600. Then, lets see what happens.

I am trying to set up a few SSL certificates in Amazon Certificate Manager, but I am trouble getting them verified after adding the CNAME in Namecheap.
Here is an example of the CNAME verification entries at Amazon Certificate Manager
Here is an example of another domains CNAME entry at Namecheap
If I put the entire value of the Name entry into Host at Namecheap, the verification fails. I also get an error on some long domains I have, as the Name entry exceeds 60 characters.
Can anyone assist with the correct parts needed to verify via DNS using Namecheap?
In the CNAME record enter - _cff0cda88701846cbe7a34cd737378e2 as the host field and - _490287b8f448e2cca3862ebb4a51591.acm-validations.aws in the value field.
Once done wait for at least 1 hour for the changes to reflect.
If anyone is looking for NameCheap DNS record validation for AWS CloudFront ssl validation then please refer screenshot below. This NameCheap DNS record validation worked for me as of Jul 2019
Adding a more complete answer.
Some DNS provider like Namecheap appends the bare domain name to the DNS record. In effect, if you add the full record provided from Amazon Certificate Manager like so (replace example.com with your domain):
_cff0cda88701846cbe7a34cd737378e2.example.com
What you'll end up with is
_cff0cda88701846cbe7a34cd737378e2.example.com.example.com
To check if this is the case, after you have added the DNS record, run this command (on Unix)
dig +short _cff0cda88701846cbe7a34cd737378e2.example.com.example.com
If it returns the CNAME record, you have to omit the domain name from your DNS record so you won't get a duplicate domain name in there. Then run
dig +short _cff0cda88701846cbe7a34cd737378e2.example.com
You should get the corresponding CNAME record from it. The validation can take up to 48 hours.
Even though AWS includes it, do not include the domain name itself in the CNAME Host field for Namecheap (they apparently append it for you); just chop that off at the end. The value field is fine.
Give it half an hour.
namecheap.com does now allow a leading underscore in the Value field.
As specified in the AWS docs' Troubleshoot DNS Validation Problems ,
you can remove the underscore from the ACM-provided value and validate your domain without it.
In your case, the Value would be:
490287b8f448e2cca3862ebb4a51591.acm-validations.aws.
Where the trailing dot should still be permitted.
For any one using a subdomain like - api.example.com.
In the CNAME record enter - _cff0cdhash.api as the host field and - _490287b8f4hash.acm-validations.aws in the value field. As namecheap itself appends example.com to it. I was not able to figure out a way to make it work for www.api.example.com.
above worked for me except for the root domain validation ; there I had to add entire string _cff0cda88701846cbe7a34cd737378e2.example.com
instead of _cff0cda88701846cbe7a34cd737378e2. for the certificate to be issued.
For the others, _cff0cda88701846cbe7a34cd737378e2.www was enough. Hope it helps. Just did this today.
My DNS service is cbeyond (MaxASP) and I want to move it to AWS route53 service.
In cbeyond I have 2 fields for TXT records: TXT record (looks like domain) and Record data.
In AWS and other DNS services I have only one field for each record (usually called "Content").
My questions is how can I copy my records to AWS? How it will identify the right data?
Thank you all!
Setting the (sub-) domain (there's a field for top at the top when you create a new entry) and providing the right content should be totally sufficient.
My TXT values look something like this, for example for mandrill._domainkey:
"v=DKIM1; k=rsa; p=..."
