After adding a new site in FlyingCDN, the status may remain as “Pending validation”. This means we haven’t been able to detect the required DNS record yet.
How validation works
FlyingCDN checks for a specific CNAME record:
_acme-challenge.your-domain.com → your-domain.com.ffb7310192aab5b6.dcv.cloudflare.com
This record is required to issue the SSL certificate. Once it’s detected, the status will automatically change to “Active”—usually within a minute.
If it’s stuck at “Pending validation”
Here are the most common issues:
CNAME proxy enabled
If you're using Cloudflare, make sure the_acme-challengerecord is set to DNS only, not proxied.Incorrect record type
You must add a CNAME record, not a TXT or other type.Old TXT record present
Delete any existing_acme-challengeTXT records if found—they can interfere with validation.CAA records set
If your domain has CAA records, remove them. These can block SSL issuance unless properly configured.Universal SSL enabled
If you're using Cloudflare, you must disable Universal SSL. It conflicts with external certificate validation
How to confirm the record is correct
You can verify that the _acme-challenge CNAME is publicly visible using any DNS lookup tool like whatsmydns.net.
It should return the value ending with your-domain.com.ffb7310192aab5b6.dcv.cloudflare.com exactly as shown in your FlyingCDN dashboard.
Once everything is in place, validation will complete automatically.
