Latest Hummmingbird update causing 403 errors when using WPMUDEV CDN

Hey Gang hope you are all well!

Am hosting on a cloud server with Cloudflare enabled.

Since the latest update today I noticed a pretty big drop in performance across the board on all sites with Hummingbird installed, but I decided to try out the minified files hosted on the dev cdn option, not sure what the issue is but i get 403 errors when its enabled and also invalid security warnings on the SSL. So i deactivated the host files on dev cdn option and the site was instantly free of errors but running slower than the last build in some cases 10-15 seconds slower on some test server locations.

Any Ideas?

In case needed the dev support login is already enabled.
