What the portals show

The portals translate the code, never the title. The English (en-GB) message, in ICU format with the arguments as placeholders:

The terms have changed. Read them again and accept them to continue.

}

Handling it

Branch on code, not on title or the status alone, and log traceId. Codes are stable; new codes may appear, so fall back on the HTTP status for a code you do not know. See Handling errors and the list of codes.
