Research direction

Start by reproducing the failed Map Network Drive connection after the reported delay, then compare its authentication behavior with a direct Cygwin ssh connection. Check the SSHFS and WinFsp versions and the Credential Manager state; done means the previously working remote connection can be re-established.

Description

Bug Report

I managed to mapped and connect to a remote server using a combination of billziss-gh/sshfs-win and winfsp.
I can browse, create files, edit files.
But a few days after, I tried to reconnect the same connection but the connection is refused.

How to Reproduce

Wait for a few days, try to reconnect, connection failed.
I tried going to Control Panel > Credential Manager > delete all entries related to sshfs.
Still failed.

Behaviors

Authentication when "Map Network Drive" seems to be rejected.
I opened Cygwin, ssh directly to my server, ensuring the same username and password, works.
