TOS-SYS-001Our problem, not yoursSomething went wrong at our end
What happened
An unexpected failure that is not your doing and has no specific handling yet.
What to do
Report this with the code and roughly what you were doing. The details are in our logs.
This one is not something you did wrong, and there is no setting you can change to avoid it.
Quote this code when reporting the problem. It identifies the exact check that failed, which the wording alone does not.
