There are similar discussions regarding the issue of answers suddenly stopping when using the DeepSeek R1 model. Here are a few relevant threads:

I use DeepSeep R1, Answer will suddenly stop when I ask question in web. - This discussion is still open and might provide insights or solutions as it progresses ^[1].
Knowledge-related responses stop in the middle of answers - This is another open discussion that might be related to your issue ^[2].
[Help] “Navigating the ‘Stop Responding’ Prompt in Applications” - This discussion is also open and could contain useful information ^[3].

The issue you're experiencing with the DeepSeek R1 model in a self-hosted environment is a known problem related to the response_format=json_object setting. After multiple interactions, the API may return empty responses. To address this, you can disable the json_object response format setting and include JSON output instructions in your system prompt instead. This approach has been shown to yield better results ^[4]^[5].
