> When I rollback to 8.11.1 with exactly the same configuration I don't experiment this issue.
> I tried:
> 1. Set the "SOLR_JETTY_HOST="0.0.0.0"
> 2. Set the "SOLR_MODULES=hadoop-auth" because it uses kerberos too.
> 3. I read the documentation about [Kerberos|https://solr.apache.org/guide/solr/latest/deployment-guide/kerberos-authentication-plugin.html] Authentication and it's pretty similar to the 8.11.1 version.
> 4. I modified my security.json like this:
