The vProxy's InventorySessions.gob files are used to store session information for the NetWorker server's nsrvisd service. The .gob extension suggests that these files are in the Go Binary format which may contain session information related to inventory management. In some instances, this file may not have been cleaned up and has cached outdated information about the vCenter credentials. In some instances, the InventorySessions.gob file may fail to be deleted during cleanup resulting in failed login attempts.

Renaming the folder /data01/runtime/state/vbackupd/ folder or deleting the .gob file is the suggested workaround.

1. Open an SSH session to the vProxy appliance and login as admin.
2. Once logged in, switch to root:

sudo su -

3. Stop the vbackupd service:

systemctl stop vbackupd

4. Rename the /data01/runtime/state/vbackupd/ directory:

mv /data01/runtime/state/vbackupd/ /data01/runtime/state/vbackupd_`date -I`.bak

5. Reload the vProxy daemons:

systemctl daemon-reload

6. Start vbackupd:

systemctl start vbackupd

A new /data01/runtime/state/vbackupd/ directory is created.
