If the local model is served via ollama, there's a default timeout of 10 minutes , which can be adjusted either per-call , or (as I did) in the systemd service environment variables

You didn't specify what was serving your local model.

Thank you for your reply. I use LM studio (local server), but can switch to a different tool.

Do you know how to switch it in LM studio?

What I see is that: android studio gives "Error: stream failed" and in LM studio server I see it is still working, then says that client (=android studio) disconnected.

So I assumed it was a setting in android studio.
