  1. Download Job logs. Refer to the Logs article.
  2. Extract the logs and navigate to the Phoenix<YYYY/MM/DD>-<timestamp>.log file and check for the following traceback in the logs.

    [2020-08-02 01:07:08,215] [ERROR] Error during backup
    [2020-08-02 01:07:08,216] [ERROR] Error <type 'exceptions.AttributeError'>:'NoneType' object has no attribute 'product'. Traceback -Traceback (most recent call last):

    AttributeError: 'NoneType' object has no attribute 'product'


Assign a valid value to the Networking field on the ESXi host so that the backup proxy can communicate with the ESXi host.
