What it means

Your customer account is not currently active. Your credentials are valid — the gateway recognised you — but traffic is administratively disabled. There are three variants with the same response code, distinguishable by the detail field.

When you'll see it

• Permanently blocked — alseda has set your account to blocked status. Typically compliance, contractual dispute, or loss of service.
• Temporally blocked — your account has a time-bounded block in effect (maintenance window, scheduled outage, compliance hold). The block has an end date which alseda can share on request.
• Deactivated — your account has been set to inactive status — for example after contract termination or a pause at your request.

Example response

HTTP/1.1 403 Forbidden
Content-Type: application/problem+json
X-Request-ID: 550e8400-e29b-41d4-a716-446655440000

{
  "type":    "https://errors.prod.prevop.alseda.eu/errors/customer-blocked",
  "code":    "CUSTOMER_BLOCKED",
  "title":   "Customer temporarily blocked",
  "status":  403,
  "detail":  "Customer is blocked until 2026-05-01T00:00:00Z"
}

How to fix

1. Read the detail field — it will name the variant (permanent block, temporal block with end date, or deactivated).
2. For a temporal block, wait until the end date shown; the gateway resumes service automatically without any action on your side.
3. For a permanent block or deactivated status, contact alseda — the fix is contractual or administrative, not technical.
4. Do not retry the request while blocked — the response will not change until the block is lifted or expires.
