Hi Kenia,

A few quick questions to help us narrow this down:

1. Were you able to chat successfully with the default model at first?
2. How did you switch to the Grok model (what exactly did you change / where)?
3. In the web UI logs, what messages or errors do you see when you send a chat?

Thanks!

1. I have succeed in my first deployment, after certain efforts. but it doesn't work again after redeployment
2. by terminal with inputting "openclaw config". I have checked the dashboard, seems it is set properly.
3. No error message, just "no one" respond" to me in the chat. Supposingedly the AI will reply me

i have created another project, and it works for a while. you can see my Zeabur AI Hub has some usage. However, it suddenly doesn't work now _

Below is the error msg i got just now. Thanks in advance.

i have created a new project. Back to original issue. No feedback from the agent, despite that zeabur AI Hub shows that requests have been made to them. I think this might be the issue of Zeabur AI Hub

Did you input your API key while creating OpenClaw via our template? For the most seamless experience we would recommend adding a the AI Hub Key while creating
