We use traducir.win to translate text for the international Stack Exchange sites, so they get properly localized.

I just tried to sign in to the Russian traducir.win and got the following error:

Enter image description here

The exception handler configured on ExceptionHandlerOptions produced a 404 status response. This InvalidOperationException containing the original exception was thrown since this is often due to a misconfigured ExceptionHandlingPath. If the exception handler is expected to return 404 status responses then set AllowStatusCode404Response to true. System.InvalidOperationException

Can you look into this so we can continue offering translations for the international Stack Exchange sites?

    Not sure who cast that close vote but to the people in the queue: traducir is a tool used for the foreign language SE sites, and questions about it definitely belong here on MSE, as it makes traducir software that powers the Stack Exchange network.

    It's still happening today (tested with pt.traducir.win + google SSO).

Traducir was a victim of some new anti DDoS measures. It's a shame it took me a bit to notice, feel free to ping me on the chat (or open an issue on the repo) if you don't see traction here.
