ICX and captive portal

Hello everybody. I’m trying to have my ICX7150 (08.0.80) working with an external captive portal. My device connected to eth 1/1/11 receives an IP address an if it manually open the captive portal page it works, but … no way to have it displayed automatically or being redirected opening another web site. Where am i wrong? Here’s the config, i’ve follwed online guide (my captive is on Cloudpath): https://ruckus-support.s3.amazonaws.com/private/documents/2478/ruckus-icx-flexible-auth-cloudpath-52-dp.pdf?AWSAccessKeyId=AKIAJM3QLNNKLOV235TQ&Expires=1557155681&Signature=n4NyA9sgP1PNx65c6iBwzc4gDAs%3DThis is my config.Current configuration:!ver 08.0.80dT211!captive-portal cloudpath  virtual-ip <myfqdn>  virtual-port 443  login-page /enroll/portal/reset!!default-vlan-id 4000!vlan 1 name Management by port tagged ethe 1/2/1 untagged ethe 1/1/1 to 1/1/10 management-vlan default-gateway  <A.B.C.D> 1!vlan 75 name Ospiti_DiRete by port tagged ethe 1/2/1 untagged ethe 1/1/11 webauth  captive-portal profile cloudpath  auth-mode captive-portal  trust-port ethernet 1/2/1  enable!vlan 4000 name DEFAULT-VLAN by port!aaa authentication dot1x default radiusaaa authorization coa enableaaa accounting dot1x default start-stop radiusaaa accounting mac-auth default start-stop radiusip address <A.B.C.D> 255.255.255.0ip dns domain-list domain.localip dns server-address <A.B.C.D>!logging console!radius-client coa host <A.B.C.D> key <key>!web-management https!interface ethernet 1/3/1 speed-duplex 1000-full!interface ethernet 1/3/2 speed-duplex 1000-full!end
