Tortoisegit couldn ' t load this key (unable to open file)

A little problem, record it.

After configuring PPK with Tortoisegit, a git repository prompts for the following error each time it is updated.

Couldn ' t load this key (unable to open file)

As shown in figure:

Solution:
Right below the corresponding warehouse, see below,

TORTOISEGIT_GEN_GITHUB.PPK is my previous generation, and later this PPK deleted, and I now use the SSH directory is DUFY_GITHUB.PPK, did not sync update this warehouse putty Key.

The update is OK for the file I currently generate. A very simple, very small point, record it.
