AUTH441: Auth token too large
What this means
The login token is larger than this server accepts.
The server rejected the login token for size: a 400 when it travels in the Authorization header, or a 414 when it travels in the URL. No client-side encoding can shrink it — the server's header/URL size limits must be raised, or the token made smaller.

Troubleshoot
- On Apache, raise LimitRequestFieldSize (header path) or LimitRequestLine (URL path) in the vhost config.
- On nginx, raise large_client_header_buffers.
- Behind a proxy or CDN, the limit may be at that layer — check both.
- If limits cannot change, contact support about issuing a smaller token for this site.
