| HTTP status | `409` Conflict |
| Retry | No |

## When it happens

The provider allows one live connection per company and environment, and the company already has it; `error.details.connection_id` is its id.

## How to fix it

Use the existing connection, or disconnect it first to create a new one.

## Retry

Do not retry. The outcome is final: sending the same request again gets the same answer.

## Returned by

The operations where this code is most likely. The list is not exhaustive.

- [`POST /v1/companies/{company_id}/connections`](/connections/createCompanyConnection)
