Add follower index error: "index_not_found_exception"

[Zeus29]

Hi,

I have 2 elastic clusters (Cluster1 and Cluster2) and I am trying to configure a follower index in Cluster2 from a leader index of Cluster1.

I have followed the next steps:

1. Add Cluster1 as remote cluster in Cluster2.
   

   

2. Configure the next users:

• In Cluster1 user "cross-cluster-user" with the role "remote-replication".
  
  
• In Cluster2 user "cross-cluster-user" with the role "remote-replication".
  
  

3. When I try to create a follower index of "newblogs" index, I have the next error:

Can't create follower index
no such index [newblogs]

• index_not_found_exception: no such index [newblogs]

The newblogs index exists in Cluster1:

My elasticsearch version is 8.3.3.

Any help will be appreciated.

Best regards.
