DoubleClick ads not working for specific domains

From: Sweden View: 4407 v1rus32 


An advertiser gave us tracking, VAST and other types of ads, which we put on our website. we have several projects with different domains, the ads are working on one of them but they are blocked on others.

I started testing to find out what was wrong and after many tries found out that the ads are not working for specific Referrer Headers.

For example here is VAST url;sz=0x0;ord=[timestamp];dc_lat=;dc_rdid=;tag_for_child_directed_treatment=;tfua=;dcmt=text/xml;dc_sdk_apis=[APIFRAMEWORKS];dc_omid_p=[OMIDPARTNER];gdpr=${GDPR};gdpr_consent=${GDPR_CONSENT_755}

which responds with XML enter image description here

but when you add header "Referer:" the response is empty html body.

Campaign manager administrator say that the domain is not flagged and also CM support team said the domain is not blacklisted in any ways.

Any suggestions about what we can do?
