hello i want to ask about sst percona cluster

previously i tried site to site using percona cluster version 8.4 with fresh installation, and it worked, then i tried to provide data from mysql standalone that had been backed up using xtrabackup on one of the site nodes.xtrabackup runs normally until the re-bootstrap process of node 1 on site A, then I try to join node 3 which is on site 3, it fails with the following statement:

innobackup.backup.log in node 1

Hi @fakhri,  
This error means the network connection between the two nodes was closed, or somehow broke. What kind of connection do you have between site A and site 3?
