ssh-agent not being found

R-4.1.2, ssh-0.8.0, credentials-1.3.2, libssh-0.9.5

I'm using keepass (password manager) and its built-in SSH agent. This agent works for all of my command-line (ssh, scp, rsync) agent-accessing tools, as well as basic windows gui utilities (e.g., winscp). It provides two styles of socket files: cygwin and msysgit, neither of which seem to work with ssh_connect, the use of either still results in R prompting me (using askpass) for the remote password.

Sys.setenv(SSH_AUTH_SOCK="c:/Users/r2/.ssh/keeagent_cygwin.sock")
# Sys.setenv(SSH_AUTH_SOCK="c:/Users/r2/.ssh/keeagent_msys.sock")
file.exists(Sys.getenv("SSH_AUTH_SOCK"))
# [1] TRUE
sess <- ssh::ssh_connect("r2@remotex", verbose = TRUE)

verbose output

It does not connect to the socket file, instead asking me to type in my remote password. When I do that, it connects successfully. With no other changes, I can use the running agent from other (non-R) tools, so the agent is running and the respective keys are loaded and available.

KeeAgent has options to confirm with the user when a client requests a list of keys or retrieves a key. This prompting never occurs, so it appears (confirming what the log suggests) that there is no attempt to connect to the agent.

Am I doing something wrong?
