# Reconnect a connector
Source: https://nordvec.com/docs/guides/troubleshooting/reconnect-integration

Fix "authentication has expired" and "access has been revoked" sync errors by reconnecting the affected connector.

When a sync reports **"Your authentication has expired"** or **"Your access has
been revoked"**, Nordvec can no longer act on your behalf at the provider. The
connection itself needs to be renewed; retrying the sync without reconnecting
will not help.

## Why this happens [#why-this-happens]

- The provider expired the long-lived credential Nordvec holds. Some providers
  do this on a fixed schedule, others after a period of inactivity.
- You changed your password at the provider, which commonly revokes all
  connected apps.
- You (or a workspace admin) revoked Nordvec's access from the provider's
  connected-apps or security settings.
- The provider rotated its security policy (for example after suspicious
  activity on your account) and invalidated existing grants.

## How to fix it [#how-to-fix-it]

1. Open **Connectors** in Nordvec.
2. Find the affected connector. It shows the error state reported by the
   last sync, and a **Reconnect** button on its card.
3. Choose **Reconnect** and sign in to the provider with the **same account**
   you originally connected. Approve every permission the provider lists;
   declining one leads to a
   [missing-permissions error](/docs/guides/troubleshooting/insufficient-scopes)
   instead.

Reconnect is also available from the connector's details at any time, not
only after an error.

Reconnecting keeps everything already synced. Do not use **Disconnect** to fix
an expired sign-in: disconnecting permanently deletes every document the
connector synced.

If you sign in with a different account than the one the connector was set
up with, Nordvec refuses the reconnect and changes nothing. To switch accounts,
disconnect the connector and connect the other account instead.

### Connectors that cannot be reconnected in place [#connectors-that-cannot-be-reconnected-in-place]

Guru, Notion, Zendesk, Freshdesk, Trello and e-conomic do not offer
**Reconnect**, because Nordvec cannot confirm that a new sign-in belongs to the
same account. For these, disconnect the connector and connect it again. Disconnecting deletes the
documents it synced, and the next sync imports them again from the start.

## What happens after reconnecting [#what-happens-after-reconnecting]

The new sign-in replaces the old one and the error clears. A sync starts
right away, and documents that failed while the connection was down are
retried; the items listed under **"Items that could not be imported"** clear
as they import successfully.

Connectors are connected per user: reconnecting renews *your* connection and
does not affect anyone else's. Only the person who connected a connector can
reconnect it, and that includes workspace admins: an admin cannot reconnect a
colleague's connector.
