Argo Tunnel + Teams

Zero Trust Cloudflare Tunnel
1

We use Cloudflare teams to connect back to our head office when working from home, however, when doing development work and running an Argo tunnel from the same computer to do dev testing of webhooks / api’s etc back to my local computer, I cannot have the cloudflare argo tunnel running at the same time as teams.

I get the message that I am already connected to the data center.

ERR Unable to establish connection. error="already connected to this server, trying another address" connIndex=2

Is this going to be an issue forever, or are you working on being able to do both?

Hello @alex6 ,

That error is expected when running cloudflared tunnel from a machine connected to Cloudflare via WARP/Teams. You can see more details in Unable to establish connection. error="already connected to this server, trying another address" · Issue #344 · cloudflare/cloudflared · GitHub

In practice, that should be harmless because you should still get 3 functional connections to our edge.

sadly though, the incoming requests don’t seem to work if I have both running?

The root cause must be a problematic tunnel configuration.

I have just tested:

  1. run WARP/Teams
  2. run a tunnel cloudflared tunnel --hello-world
  3. access the tunnel (with the URL that cloudflared prints), and it works fine

Can you try to reproduce this?

I’m feeling a right idiot now - thats what I was doing last night, and could not get to the tunnel, but today it works.

Accept my sincerest apologies for wasting your time!

No problem; glad it worked out!
