Connect Custom Domain with Hostinger/CloudFlare
If you are using Hostinger and facing issues with Custom Domain then you might need to add Google’s CAA records to solve the issue. CAA records are DNS records that specify which certificate authorities are allowed to issue SSL/TLS certificates for a domain.
For this issue, you need to add two CAA records in your Hostinger control panel. One with issue Tag and another with issuewild Tag. Everything else is similar for both records.
To create a CAA record, follow the given steps:
Login to your Hostinger account and access the dashboard or control panel.
Go to your DNS Zone Editor. This is where you manage your DNS records.
Scroll to the Manage DNS records section and give the following info:
Type: CAA
Name: @
Flag: 0
Tag: issue/issuewild
CA domain: pki.goog
TTL: Keep the default value of 14400 seconds
Remember to create two different CAA records keeping everything the same except the Tag field.
[Note: If you use Cloudflare, set the Proxy status to DNS only for all records.]
