It sounds like you're having a proxy-related headache

To validate SimpleProxy's status, you can try the following:

1. **Check the logs**: Look for any error messages or warnings related to SimpleProxy in the miner's logs. If it's running, you should see some activity.

2. **Verify the configuration**: Double-check that your SimpleProxy setup is correct and matches the documentation. Make sure all settings are accurate, including the gateway URL (which is already reported to be working by Datum).

3. **Run a diagnostic test**: Run the miner with the `--diagnostic` flag followed by `simpleproxy`. This will help you identify if SimpleProxy is actually running or not.

Example:

```bash

miner --diagnostic simpleproxy

```
