Describe the Bug

The Nextcloud Dashboard becomes inaccessible when the integration_openai app fails to connect to its configured backend service. This occurred after an NVIDIA driver update caused the backend service (Ollama in Docker/WSL2) to fail due to CUDA compatibility issues. Despite the backend being non-critical and used only for document summarization, its failure blocks the entire dashboard.

Error logs repeatedly show:

GuzzleHttp\Exception\ConnectException: cURL error 7: Failed to connect to [host] port [port]: Connection timed out

Other functionalities such as WebDAV and the Nextcloud mobile app remain operational.

Expected Behavior

The integration_openai app should handle backend connection issues gracefully.
The dashboard should remain accessible even if the backend service for the app is unavailable.

To Reproduce

1. Enable the integration_openai app in Nextcloud.

2. Configure it to connect to a backend service, such as Ollama running in Docker/WSL2.

3. Simulate a failure in the backend:

   Stop the Docker container.
   Introduce network issues.
   Update the NVIDIA driver, causing CUDA to stop working in WSL2 (as happened in this case).

4. Attempt to access the Nextcloud Dashboard.

I've experienced this too. I could access the login page, but the rest of the NextCloud was completely inaccessible. It would just timeout. Disabling this app fixed the problem.
