SQL Sever Replication

Dear All,

We have 3 Servers with same Database.

Server 1(SQL Servr 2014) is a Distributor and configured both Server 1 and Server 2 as Publishers.

Server 2 (SQL Server 2008R2) is now acts a publisher and Server 1 is a Subscriber with Transactional Replication.

We are now using the same Server 1 Subscriber to publish the same Database to Server 3(SQL Server 2008R2) Subscriber for Merge and Transactional Replication.

We are encountered with following Errors
