Alfresco Community 7.1 Cannot Authenticate with Keycloak Server when Keycloak use Self Sign Certificate

Question

I have test Alfresco Community 7.1 with Keycloak. My Keycloak use https (self signed certificate)

My alfresco-global.properties (Alfresco Repository)

authentication.chain=identity-service1:identity-service,alfrescoNtlm1:alfrescoNtlm
identity-service.enable-basic-auth=true
identity-service.authentication.validation.failure.silent=false
identity-service.auth-server-url=https://192.168.10.25/auth

identity-service.realm=guru
identity-service.resource=alfresco-client
identity-service.public-client=true
identity-service.ssl-required=none

csrf.filter.referer=https://192.168.11.22:443
csrf.filter.origin=https://192.168.11.22:443/*

aims.enabled=true
aims.realm=guru
aims.resource=alfresco-client
aims.authServerUrl=https://192.168.10.25/auth
aims.publicClient=true

My share-config-custom.xml (Alfresco Share)

<alfresco-config>

   <config evaluator="string-compare" condition="Users" replace="true">
      <users>
         <username-min-length>2</username-min-length>
         <password-min-length>3</password-min-length>
         <show-authorization-status>false</show-authorization-status>
      </users>
      <enable-external-users-panel>false</enable-external-users-panel>
   </config>


   <config evaluator="string-compare" condition="AIMS">
     <enabled>true</enabled>
     <realm>guru</realm>
     <resource>alfresco-client</resource>
     <authServerUrl>https://192.168.10.25/auth</authServerUrl>
     <sslRequired>none</sslRequired>
     <publicClient>true</publicClient>
   </config>

</alfresco-config>

When I start alfresco with docker compose command. It show error like this

But if I use another Keycloak Server on Public Cloud with Valid Certificate (Lets Encrypt) It can work without problem.

My Question is, How to configure alfresco to use with Keycloak Internal Server which use Self Sign Certificate.

Thank you
