Could you please try version https://github.com/ashkulz/NppFTP/releases/tag/v0.29.2 (v0.30.0-v0.30.2 are set back to draft/beta version due to issue #265 Regression for FTPES, FTPS on directory changes).

This version contains https://www.libssh.org/2019/10/25/libssh-0-9-1/ which contains multiple SFTP related fixes.

But probably the ppk format is the problem, see https://stackoverflow.com/questions/26900746/libssh-trying-to-authenticate-with-public-and-private-keys and https://the.earth.li/~sgtatham/putty/0.73/htmldoc/Chapter8.html#puttygen-conversions

Issue was indeed the ppk key. I used the normal OpenSSH privatekey and now I can connect.
