Problem with upgrade from 13.1.3.3 to 13.1.3.6

Hi joyride_us,

I may have encountered this problem before. I think the configuration contains kedh keyword.

You must remove kedh keyword or replace it to edh.

If cipher is not kedh, you can remove or change the corresponding cipher in configuration.
