Hi Team,
Product
SiteMinder 12.8 sp6
OS: Windows Server 2016
SSO product: CA Single Sign-On 12.8 sp6 (Policy server and Access Gateway server are both configured as one machine)
Policy store, user store, session store: RDBMS (SQL Server Azure VM (SQL Server 2016 SE SP2))
Deploy the above on Azure and use CA Access Gateway's OpenID Connect to build an authentication infrastructure that operates as an OpenID Connect Provider.
Question
The following error occurred when logging in to the authentication infrastructure (SiteMinder) from an application.
Please tell me the cause, scope of impact, and countermeasures.
[ERROR][xxxx-xx-xx --:--:--] org.springframework.boot.web.servlet.support.ErrorPageFilter - Forwarding to error page from request [/login/oauth2/code/web] due to exception [An error occurred while attempting to decode the Jwt: Couldn't retrieve remote JWK set: org.springframework.web.client.HttpServerErrorException$BadGateway: 502 Bad Gateway: "<html><EOL><EOL><head><title>502 Bad Gateway</title></head><EOL><EOL><body><EOL><EOL><center><h1>502 Bad Gateway</h1></center><EOL><EOL><hr><center>Microsoft-Azure-Application-Gateway/v2</center><EOL><EOL></body><EOL><EOL></html><EOL><EOL>"]
