Unable to terminate WSO2 IS sessions - session

Question

I previously had issues with WSO2 IS active-sessions-limit-handler not working. It was resolved by a previous question I asked (I upgraded to 5.11.0).
Now the issue is that when I follow this guide and setup an active-sessions-limit-handler for an SP, the server knows when I exceed the limit, but it is not able to deal with the situation correctly.
I have the max number of sessions set to 2, so when I try and login with the same user for a third time WSO2 correctly knows it is now over the limit. The issue is it gives me the following screen:
When I select any of the 3 presented options, I get an Authentication Error and the login fails. If I go to the My Account page for the user I can see that the sessions are active that are expected to be.
It seems like WSO2 is unable to retrieve the active sessions. When this error happens, I also see the following error log which appears to be that WSO2 is making a call to it's own API that is being rejected as unauthorized:
java.io.IOException: Server returned HTTP response code: 401 for URL: https://HOST:9443/api/identity/auth/v1.1/context/916aff37-aaf8-464c-bede-7f249279ff1a
Do I need to configure anything differently for the API to not return a 401? I haven't been able to find any open issues that seem to be the same problem.
EDIT, adding full stacktrace:

Try the scenario by uncommenting the <context-param> block with the name AuthenticationRESTEndpointURL in <IS_HOME>/repository/deployment/server/webapps/authenticationendpoint/WEB-INF/web.xml file.
<!-- *************** Authentication REST API URL Configuration ********************** -->
<context-param>
<param-name>AuthenticationRESTEndpointURL</param-name>
<param-value>https://localhost:9443/api/identity/auth/v1.1/</param-value>
</context-param>
<!-- *************** End of Authentication REST API URL Configuration ********************** -->```
