Issue/Introduction

Layer7 gateway deployed in APP subnet ( internal/private) exposed to internet via DMZ layer where we have nginx webserver deployed , so flow from internet is as follows:-

 

URL( https/443) --> nginx ---on https(443) --> layer7 (https/443 )  

Calling /oauth/v2/token via nginx flow gets no token back a blank response.

In reviewing the logs we see stack:

Environment

Resolution

If possible you can remove the cookie attribute from Nginx as a proxy.

You can work around this by doing the following in the /oauth/v2/token with the below additional logic:

At least one assertion

     Manage cookies assertion

          Remove=Path

     Continue Processing
