Hi,

I am working with a Azure Front Door.

I added as backend a VM where my web application is hosted.
With open 443 port when i type frontdoor URL i am redirect to website (seeing in navbar vm url address).

If i close port 443, also if i added in VM network security rules to allow traffic from frontdoor

    @Erasmo Solazzo This is the rule I have for the VMs NSG and it accepts FD requests. Can you confirm your NSG has a similar rule for 443 traffic? Thanks!
