Does Codex Cloud support SSH over Tailscale?

I configured Tailscale on my VPS and added a reusable, ephemeral auth key to Codex Cloud’s VPN settings. I published the environment and started a new task, but haven’t established an SSH connection. HTTP testing returned “connection refused,” and HTTPS returned a certificate mismatch when using the Tailscale IP. SSH works from my PC. Does Codex Cloud support SSH/raw TCP over Tailscale, or only HTTP/HTTPS? If SSH is supported, what additional configuration is required?
