# Consul Troubleshoot Proxy
Command: `consul troubleshoot proxy`
The `troubleshoot proxy` command diagnoses Consul service mesh configuration and network issues to an upstream. For additional information about using the `troubleshoot proxy` command, including explanations, requirements, usage instructions, refer to the [service-to-service troubleshooting overview](/consul/docs/troubleshoot/troubleshoot-services).
## Usage
Usage: `consul troubleshoot proxy (-upstream-ip <ip>|-upstream-envoy-id <envoy-id>) [options]`
This command requires `-envoy-admin-endpoint` or `-upstream-ip` to specify the upstream.
#### Command Options
- `-envoy-admin-endpoint=<value>` - Envoy admin endpoint address for the local Envoy instance.
Defaults to `127.0.0.1:19000`.
- `-upstream-ip=<value>` - The IP address of the upstream service; Use when the upstream is reached via a transparent proxy DNS address (KubeDNS or Consul DNS)
- `-upstream-envoy-id=<value>` - The Envoy identifier of the upstream service; Use when the upstream is explicitly configured on the downstream service.
## Examples
The following example illustrates how to troubleshoot Consul service mesh configuration and network issues to an upstream from a source proxy.
```shell-session
$ consul troubleshoot proxy -upstream-ip 10.4.6.160
==> Validation
✓ Certificates are valid
✓ Envoy has 0 rejected configurations
✓ Envoy has detected 0 connection failure(s)
✓ Listener for upstream "backend" found
✓ Route for upstream "backend" found
✓ Cluster "backend.default.dc1.internal.e08fa6d6-e91e-dfe0-f6e1-ba097a828e31.consul" for upstream "backend" found
✓ Healthy endpoints for cluster "backend.default.dc1.internal.e08fa6d6-e91e-dfe0-f6e1-ba097a828e31.consul" for upstream "backend" found
✓ Cluster "backend2.default.dc1.internal.e08fa6d6-e91e-dfe0-f6e1-ba097a828e31.consul" for upstream "backend" found
! No healthy endpoints for cluster "backend2.default.dc1.internal.e08fa6d6-e91e-dfe0-f6e1-ba097a828e31.consul" for upstream "backend" found
-> Check that your upstream service is healthy and running
-> Check that your upstream service is registered with Consul
-> Check that the upstream proxy is healthy and running
-> If you are explicitly configuring upstreams, ensure the name of the upstream is correct
```
The following example troubleshoots Consul service mesh configuration and network issues from the local Envoy instance to the given upstream.
```shell-session
$ consul-k8s troubleshoot proxy -upstream-envoy-id db
==> Validation
✓ Certificates are valid
✓ Envoy has 0 rejected configurations
✓ Envoy has detected 0 connection failure(s)
✓ Listener for upstream "db" found
✓ Route for upstream "db" found
✓ Cluster "db.default.dc1.internal.e08fa6d6-e91e-dfe0.consul" for upstream "db" found
✓ Healthy endpoints for cluster "db.default.dc1.internal.e08fa6d6-e91e-dfe0.consul" for upstream "db" found
If you are still experiencing issues, you can:
-> Check intentions to ensure the upstream allows traffic from this source
-> If using transparent proxy, ensure DNS resolution is to the same IP you have verified here
