What's Wrong?
Description
Artifacts (accessed via claude.ai/code/artifact/...) frequently fail to load. Instead of rendering the artifact content, the page shows a broken-file icon with the message "Connection reset".
What Should Happen?
Expected behavior
The artifact should render its content consistently without connection errors.
Environment
- Browser: [ e.g. Chrome, 152.0.7977.65]
- OS: [Mac]
- Workspace/team: appears to be a team project ("Case & Workflow Middle Office")
- Frequency: [hign]
- Approximate times observed: [10+]

Additional Information
Additional notes
This appears to be a backend/network stability issue with the artifact-serving service rather than a client-side rendering problem, since the surrounding page UI loads fine but the artifact content itself fails.
