as of recent i started getting \"PuTTY Fatal Error: Disconnected: No su

Answer 1

I experienced this problem because my GIT_SSH was pointing to the TortoiseSVN version of Plink.exe. I changed it to point to the TortoiseGit version, restarted cmd and it worked.

I can't remember exactly, but the TortoiseSVN version might have been 32-bit version, and the TortoiseGit version was 64-bit (located in Program Files, not Program Files (x86)).

Double-check your GIT_SSH env var.

I prefer to use git with normal cmd.exe (in Console2 of course)
