# Connection health

> Spot a connection that is about to lapse or already broke, and renew it.

> **Find it in** **Inbox** in the left menu, and the Inbox band on Home. **Last updated** 9 Oct 2026.

## Overview

Ad networks expire Epsilo's access from time to time. When a connection is about to expire or has stopped working, Epsilo puts a row in your Inbox with a **Renew** button. Renew it and Epsilo keeps reading and operating that ad account.

## How it works

**1. Epsilo watches each connection**

Each ad account carries its connection status. An expiring one is tagged **Token expiring**.

**2. Inbox tells you**

A row names the ad account and says what is wrong.

**3. You renew**

**Renew** opens that network on **Settings** > **Ad accounts**, where you approve access again.

## Use it

### Renew a connection that is about to expire

1. Open **Inbox**. Look for "(ad account) connection expires soon" with "Token expiring • Epsilo loses access when it does".
2. Select **Renew**.
3. Approve access on the network again.

### Fix a connection that stopped working

A row reads "(status) • writes fail until renewed", for example "Reauth required". Until you renew, changes from Epsilo to that ad account fail. Select **Renew** and approve access again.

### Reauthorize from the ad account

On an ad account that needs it, a banner shows its status with a **Reauthorize** button. It opens the same connect page.

### Finish a connection you started

If a connection never finished, Inbox shows "setup never finished" with **Finish setup**. Select it to pick up where you left off.

## FAQ

> [accordion] Why did a connection lapse?
>
> Networks set how long access lasts. Epsilo cannot extend it for you; renewing approves access again on the network.

> Check the ad account's status in Portfolio > **Ad accounts**. If it still looks connected, email [support@epsilo.io](mailto:support@epsilo.io) with the ad account name.
