I want to use the doubleclick for publishers to serve ads from multiple networks on my website as well as sponsored ads. I have gone through all the process of setting up the different orders, line items and creative to run and added the ad unit supposed to display the campaign on my website. The problems the ads don't show up. When I debugged I got the error "ad units failed to fetch", "ad units failed to render" but if I call the ad units on a fresh html file, it fetches and renders. I have searched all through the internet for a solution but can't find any. Please I need help to get this fixed once and for all.

make sure the call to server to render the ads on the webpage is correct. check the url very well.

as you have explained earlier on, it should work.
