SQL Server Data Replication Problems

You have configured the publishing database in the SQL Server of your machine and created a publication named pubs: stores.
At the same time, the subscription database mypubs (empty database generated according to the pubs script) is designed on the same machine ).
Everything is OK. After testing, all insert, delete, and update operations in the pubs database can be normally reflected in mypubs.

However, the problem occurs. In the database system of another machine (with different domains), during the subscription request operation, select publish, after you click the machine on which the server is deployed, the published content is not displayed. As a result, you cannot perform the next operation.

Why? I wonder if anyone has encountered the same problem? Can anyone help me solve this problem?
