How to fix error: Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true

Yes. I read about this error a lot of info. Nothing helps me.
My server Ubuntu with Apache2, PHP.
My website has to start a video from video.onnetwork.tv. But I get an error
“Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true”

I updated .htaccess:
Header set Access-Control-Allow-Origin "video.onnetwork.tv"

Same error.

Header set Access-Control-Allow-Origin "https://video.onnetwork.tv"

Same error.

Header set Access-Control-Allow-Origin "onnetwork.tv"

Same error.

Header add Access-Control-Allow-Origin "video.onnetwork.tv"

Same error.

Header add Access-Control-Allow-Origin "video.onnetwork.tv"

Header set Access-Control-Allow-Credentials true

Same error.

SetEnvIf Origin "http(s)?://(.+.)?onnetwork.tv(:d{1,5})?$" CRS=$0

Header always set Access-Control-Allow-Origin "%{CRS}e" env=CRS

Header merge Vary "Origin"

Same error.

Apache2 has enabled .htaccess.
headers enabled.

In PHP added
header("Access-Control-Allow-Origin: https://video.onnetwork.tv");

Same error.

Added these settings to apache Virtual Directory, restarted Apache2 – same error.

I don’t know what to do. How I can fix this error?
