title: Private location HMAC errors

## Problem

One of your Synthetics Job Managers is failing checks and is reporting one of these errors:

```
HMAC MISMATCH ERROR: HMAC mismatch between saved HMAC and calculated HMAC at job run time
```

```
HMAC MISMATCH ERROR: HMAC expected but missing from Job metadata
```

These errors indicate an error with [verified script execution](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/private-locations/verified-script-execution-private-locations).

## Solution

You will need to input the correct password for the location from which this check is failing.

To input the password:

1.  In **[one.newrelic.com > Synthetic monitoring](https://one.newrelic.com/synthetics-nerdlets)** > select the failing monitor.
2.  Go to **Settings > Script**.
3.  In the location password fields, submit the correct password.

> #### 💡 TIP
>
> New Relic does not store the private location passwords. If you don't know the password, find the person on your team that configured the private location. If it is not possible to recover the password, your only option is to create a new private location.
