Cause

bptestbpcd test from master server is not actually connecting from the master server to the client server.
Instead, the connection is being made locally on the client itself (127.0.0.1), and the client is rejecting itself as an authorized server.

There is a micro time difference noted in the bpcd logs and due to that .json file expires within few seconds.

Solution

1. Uninstall the existing NBU client agent from the client server.

2. Delete the veritas folder from installpath\netbackup\veritas

3. Reboot the client server.

4. Download a fresh NBU 10.0.0.1 client binary and install it on the client server.

5. Once NBU 10.0.0.1 is installed successfully, stop all the NBU services on the client server.

6. Install EEB 4102039 on the client server.

7. Start all the NBU services on a client server.
