On a Linux VM with two different network cards, where DUAS has been installed as a Cluster with the secondary IP / secondary hostname, the autopatch does not work as it tries to connect to the primary IP address.

The Autopatch status remains in Upload In Progress, and the uxdqmlan generates a defunct process.

Two options:
1. Setting the variable U_CLUSTER to N before launching the autopatch and setting it back to Y after the upgrade.
2. Upgrading the node with the kit from the system and not via the autopatch.
