[Hummingbird] Resources dont load(images, google maps etc) when using Hummingbird CDN option

When enabling the WMPUDEV CDN option in Hummingbird, images dont load. To reproduce: enable CDN option, clear cache on cloudflare and hummingbird - wait 1 min and reload the page. The page speed insights and gtmetrix do get a boost in the score, but that doesnt help if the site actually looks like shit since front page image is missing for example. please advise
