GitHub action waits forever and then times out

[beaugunderson]

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.
