@chouston @andrew chen I had a same problem in Ranger UI with Knox SSO, I did following
1.Changed Ranger external url from http://<xxxx>.<xxx>:6080 to http://<xxxx>.<xxx>.<xx>:6080
2.Changed SSO provider url from https://<xxxx>.<xxx>:8443/gateway/knoxsso/api/v1/websso to https://<xxxx>.<xxx>.<xx>:8443/gateway/knoxsso/api/v1/websso 3. set knoxsso.cookie.secure.only=false in Knoxsso topology. 4. changed knoxsso.redirect.whitelist.regex property in knoxsso topology to support new host. I am able to open ranger UI after above changes :).
