1. Run the `consul troubleshoot upstreams` command to retrieve the upstream information for the service that is experiencing communication failures. Depending on your network’s configuration, the upstream information is either an Envoy ID or an IP address.
```shell-session
$ consul troubleshoot upstreams
```shell-session
$ consul troubleshoot upstreams
==> Upstreams (explicit upstreams only) (0)
==> Upstreams IPs (transparent proxy only) (1)
[10.4.6.160 240.0.0.3] true map[backend.default.dc1.internal.e08fa6d6-e91e-dfe0-f6e1-ba097a828e31.consul backend2.default.dc1.internal.e08fa6d6-e91e-dfe0-f6e1-ba097a828e31.consul]
If you cannot find the upstream address or cluster for a transparent proxy upstream:
- Check intentions: Tproxy upstreams are configured based on intentions. Make sure you have configured intentions to allow traffic to your upstream.
- To check that the right cluster is being dialed, run a DNS lookup for the upstream you are dialing. For example, run `dig backend.svc.consul` to return the IP address for the `backend` service. If the address you get from that is missing from the upstream IPs, it means that your proxy may be misconfigured.

1. Run the `consul troubleshoot proxy` command and specify the Envoy ID or IP address with the `-upstream-ip` flag to identify the proxy you want to perform the troubleshooting process on. The following example uses the upstream IP to validate communication with the upstream service `backend`:
