Environment

This affects Security Analytics version 8.1.3 and 8.2.1

Cause

This is caused by a conflict between python version 2 and version 3.

Resolution

You can generate the storage log bundles manually using the following SFTP commands:

1. sftp -o 'KexAlgorithms diffie-hellman-group16-sha512' -P 1022 <username>@<IPaddress>
2. Enter password at "Password: " prompt
3. Enter " get logs <desired file name>" at "sftp>" prompt. The space before "get" is important.

This should be resolved in Security Analytics version 8.2.3 and greater.
