I’m running two keycloak docker instances and configured cluster as specified here [Docker Hub](https://hub.docker.com/r/jboss/keycloak/)

I can able see logs related to clustering and two records in `JGROUPSPING` table. Also it works when authenticate(openid-connect) through Host1 and get access token/refresh token and able to retrieve new access\_token using refresh token via Host2, which means I believe clustering setup is working.

But Im getting 401 error when I make API call to Host2 either using the access token I received from Host1 or access\_token I got from Host1’s refresh token. It works only when I use access\_token received from same host.

My understanding is that these access\_tokens doesn’t related to cookie it should be working seamlessly. But it fails.
