Warning

Authentication required

A request reached the platform without a valid authorization token. This is usually transient SDK plumbing during start-up or reconnect.
Authentication & licensingAlso known as: MISSING_AUTH, authentication-required, AUTH_HEADER_MISSING

Symptoms

API response error_code: MISSING_AUTH (HTTP 401).
Brief authentication warnings in the Experts log during reconnect.

Causes

The session token was not yet issued or was cleared during a reconnect.
A network proxy stripped the Authorization header.

How to fix it

1
Let the SDK retryThe SDK re-authenticates automatically. If the product keeps failing, remove and re-add it so a fresh session starts.
2
Check for a corporate proxyIf you run MetaTrader behind a proxy or VPN that rewrites headers, allow direct HTTPS to themarketrobo.com.
