Cause

All Notification Server timeouts were analyzed and found to be set well past the interval that the timeout is noticed in. In this case, a proxy server was configured in the environment with a low timeout value which caused the replication to fail.

Resolution

Disable the configured proxy.

Once the proxy server was removed from the test environment, the replication completed successfully.
