Solution 2:
Hi I was able to solve it using this code
<IfModule mod_headers.c>
SetEnvIfNoCase Origin "https?://(www\.)?(xyz\.com|video\.xyz\.com)(:\d+)?$" ACAO=$0
Header set Access-Control-Allow-Origin %{ACAO}e env=ACAO
</IfModule>
Solution 3:
It looks like you may be specifying the origin incorrectly. Try this instead:
Header set Access-Control-Allow-Origin "https://video.xyz.example"
