During the replication of backups from the onsite environment (without public internet) to the offsite storage (with public internet), the job failed with error 16010. Although we have confirmed that port 22711 on the offsite storage is accessible, the error log from the backup system's Copy_task_server indicates:
[ERROR:16010#rpc init error]: Task<91b91733-539f-46db-b91e-d21cb39f2c4e> test connection to copy_server error, remote ip :192.168.11.24, port :22711
