This seems to have just started this week with no code or config changes on my side - the linkedin OAUTH connect/login api breaks on my localhost node app - here is the console error on browser:
Refused to get unsafe header "X-CDN"

I cannot reproduce this on a public DNS site with the same code only localhost. any clues?
