Intermittently, Gpg4win fails to log in under the service account

Use Case:

  • A scheduled automated job invokes the PGP encryption executable at runtime.
  • This job runs under the context of a dedicated service account, which is configured for auto-login on a Windows server.
  • The same service account is also used by other third-party applications in similar automated processes, all of which function without issue.

Issue:

  • Intermittently , Gpg4win fails to log in under the service account.
  • We’ve been unable to identify a clear root cause, and other processes using the same account continue to operate normally.

Hello @Dan1, which version of Windows and which of Gpg4win are you using?
