Our Adobe Campaign worked without issues until recent update. Now landing pages cannot fetch header image. When I upload new header image to brand, system doesn't save them. Only thing that is working correctly is newsletter delivery item because it uses image from AEM instance. Every image in Campaign instance in unreachable. Any ideas?
In order to verify if this is related to server configuration, Could you view the source of the delivery and then try to open the image url directly in a browser like Chrome and if it shows error message like "Access Denied" then you would need to raise a support ticket on our support portal so our team can liaise with Infrastructure team to get that rectified.
