I know this is not a standard Webinoly support type issue but if you have an idea what might be causing this problem, I would be very glad to hear it.
I have tried 3 different CDNs and 4 different CDN enablers, with or without a custom domain, and the pull zones simply don't pick up any files from the Pull Zone when its on Webinoly.
As a test I tried a couple of free trials with hosting companies and with the site migrated to the new host the CDN started to work.
I have tied everything I can think of including deactivated the firewall, but nada!
The only time a CDN works on this site is when the site was NOT on Webinoly.
Is there perhaps something in the NginX Content Security Policy (CSP)/ response headers which could be causing this?
Unfortunately there is nothing in the CDN logs (empty) to help me.
Any ideas?
