Looks like the token session isn't valid.

Hi everybody,

Could  you help me please with a hard nut to crack? We have the following situation:
When calling the userinfo endpoint over an enterprise proxy server (js adapter loadUserInfo() method):

https://hostname/auth/realms/realmname/protocol/openid-connect/userinfo

we get 403 Forbidden with no Access-Controls headers set. Here is the funny part - it happens only in Chrome, Firefox and Opera. With Safari and IE11 it seems to be working. 

The stacktrace from server.log does not tell me much....:
