Information
HTTPS protocol protects the integrity and confidentiality of data between the client and the server.
Encrypting the communication between the OpenID Connect relying part and the OpenID Connect server provider using HTTPS protects sensitive information.
Solution
Add the httpsRequired attribute to the openidConnectClient element to ${server.config.dir}/configDropins/overrides/*.xml and set it to true to ensure that security transport is used for JSON Web Tokens.
<openidConnectClient httpsRequired="true" />
