Cloudflared not initiating rdp connection through Argo Tunnel

Trying to reach a server with rdp through the Cloudflare network. We use the linux appimage on server and client and this tut: . But when running:

cloudflared access rdp --hostname --url localhost:8081

on the client it only says “Started listening on”

No browser window is opened nor is there any url posted on the command line.
Looking at the network traffic cloudflared does not seem to initiate a connection to the Cloudflare network at all. However, when using other commands the daemon works, so not a network issue. Any ideas for troubleshooting?

were you able to resolve this? I have same issue.
