# The chat is not working > Source: > Published: 2026-10-31 00:24:53+00:00 Hmm… if you’re referring to `HuggingChat Omni`, I wonder if `the October 30 fix` might be relevant: There was a [temporary fix for a live HuggingChat production problem on October 30, 2026](https://github.com/huggingface/chat-ui/pull/2742). A maintainer reported that some DeepSeek Flash requests were routed to a provider that rejected the configured output-token limit. The temporary configuration change was merged that day, with successful tests reported for the adjusted setting. **It might be related, but it doesn’t establish what happened to your two failing projects.** We don’t yet know whether you’re using HuggingChat Omni, which models are involved, or whether the error is still happening. That same message can appear for different reasons, including a failed inference request, an issue with a particular conversation, or a problem in another application. **The lowest-effort route I’d suggest:** I wouldn’t top up again, delete the original work, reset a Space, or change a spending limit just to see whether the message goes away. The fact that **two work and two don’t** is already a useful starting point. The optional sections below give the possible branches and sources in more detail; none requires you to carry out every check. A small, safe comparison if the problem continues The two most helpful details would be whether **the error still occurs** and what you mean by the four **“projects.”** If a model name or safely redacted error code is already available, that may narrow it further, but there’s no need for another payment or a lengthy debugging session just to reply.
