# terminal_unavailable

> Signal webhook: the terminal did not answer a read the plan needs.

Source: https://tickwire.io/docs/errors/terminal_unavailable/

HTTP 503. Nothing reached the broker.

**Likely cause:** The terminal is down or restarting, so its symbol details, account information, positions or price could not be read.

**What to do:** Nothing was sent. Check the account's health, then send a new alert.

**Retry:** No. The same request gets the same answer; change something first.
