As the fix for this won't be part of 8.3.1, running the following from the **browser console** when **logged into the Gateway** will perform the noted action. The change will take effect immediately without having to restart the Gateway.

**Regenerate the Ignition OPC UA Server Certificate** :

```python
var csrf;

await fetch('/data/app/session', {
    method: 'get',
    headers: {'Accept': 'application/json', 'Content-Type': 'application/json'},
}).then(response => response.json()).then(data => {csrf = data['csrfToken'];});

await fetch('/data/opc-ua/api/v1/server/certificate/regenerate', {
    method: 'post',
    body: JSON.stringify({validPeriodDays: 1095}),
    headers: {'Content-Type': 'application/json', 'X-CSRF-Token': csrf}
}).then(response => response.json()).then(console.log);

```

**Regenerate the OPC UA Client Certificate** :

```python
var csrf;

await fetch('/data/app/session', {
    method: 'get',
    headers: {'Accept': 'application/json', 'Content-Type': 'application/json'},
}).then(response => response.json()).then(data => {csrf = data['csrfToken'];});

await fetch('/data/opc-ua/api/v1/client/certificate/regenerate', {
    method: 'post',
    body: JSON.stringify({validPeriodDays: 1095}),
    headers: {'Content-Type': 'application/json', 'X-CSRF-Token': csrf}
}).then(response => response.json()).then(console.log);

```
