GitHub action waits forever and then times out

We use a relatively simple config:

      - name: Tailscale
        env:
          TAILSCALE_AUTHKEY: ${{ secrets.TAILSCALE_AUTHKEY }}
          TAILSCALE_EXIT_NODE_IP: ${{ secrets.TAILSCALE_EXIT_NODE_IP }}
        uses: tailscale/github-action@v4.1.1
        with:
          authkey: ${{ env.TAILSCALE_AUTHKEY }}
          args: --exit-node ${{ env.TAILSCALE_EXIT_NODE_IP }}
          ping: ${{ env.TAILSCALE_EXIT_NODE_IP }}

But our GitHub action pauses forever waiting for something to happen:

Any ideas? The exit node is working (verified via setting my local Tailscale to use it), and this seems to be happening only the last couple of days.

Start with the workflow snippet and the Tailscale action logs around the hang, checking the v4.1.1 authkey, --exit-node, and ping inputs. Reproduce the timeout with the supplied configuration; done when the action completes the connection and ping or reports an actionable failure instead of waiting indefinitely.
