A record problem for vpn subdomain

Hi everyone, first of all, sorry for my english, it’s not my main language :wink:

I’m trying to “proxy” a “A Record” for a subdomain who is redirected to my Fortigate firewall for the SSL Vpn connection. Url is: vpn.example.com. When I proxy the record, it doesn’t work. When I unproxy the record, it’s working. I have the same exact problem for my ArcGIS server. My question is, is it more a Cloudflare configuration problem or my firewall with country restriction? Thx all

One more info, I’m using an SSL VPN connection with the the Forticlient

I found the problem over the forum. For other, we need spectrum and it’s not include in the pro account.
