How long request for SSL certification takes?

When requesting an SSL certificate through AWS Certificate Manager (ACM), the verification process typically completes within minutes to a few hours after you've properly set up the DNS records. However, in some cases, it can take longer.

Here are some key points about the certificate verification timeline:

• ACM certificate requests that aren't validated within 72 hours will time out and fail
• While the documentation states it may take up to 72 hours, in practice, validation often happens much faster - typically within minutes to 30 minutes when DNS records are correctly configured

Since your certificate has been pending verification for 2 days, there's likely an issue with your DNS configuration. Here are some troubleshooting steps:

1. Verify that you've correctly added the CNAME records provided by ACM to your DNS configuration
2. If using Route 53, check if you used the "Create records in Route 53" button to automatically add the records
3. If using a different DNS provider, ensure you've copied the record name and value accurately
4. Check that your DNS records have propagated using tools like dig or nslookup
5. Verify that your domain's nameservers are correctly configured

If the verification continues to fail after 72 hours, you'll need to:

1. Delete the failed certificate request
2. Request a new certificate
3. Add the new CNAME records to your DNS configuration

As an alternative, you might consider using email validation instead of DNS validation if you continue to experience issues.
