# 54056: Account cannot access requested Service Instance

Log Level: ERROR

## Description

Account cannot access requested Service Instance.

### Possible causes

* The requested Sync Service does not belong to this account.
* You have multiple accounts, and this Sync Service does not belong to the account whose credentials you used.

### Possible solutions

Confirm that you're using the correct credentials for this instance's account. This could mean:

* Make sure the Access Token specifies the correct Account SID
* Make sure that the Account SID + AuthToken pair you're using (for REST access) matches the correct account
* Make sure the API Key + API secret you're using (for REST access) belongs to the correct account.
