Ollama Is Installed but Not Running

What does this problem usually mean?

A local AI app can find the Ollama installation and still fail because the Ollama process or service is not active.

What to check first

1. 1

   Confirm that the Ollama application or service is active.

2. 2

   Try a simple local model request rather than relying only on the tray icon.

3. 3

   Check whether another process is using the expected port.

4. 4

   Review recent Ollama output or logs for an obvious startup error.

5. 5

   Restart Ollama and verify the endpoint again.

Important: verify the result

Change one thing at a time and repeat the same test afterwards. A successful command is not proof of a fix; verify that the original failure can no longer be reproduced.

Note: Provider features, limits and versions can change. For version-specific questions, always verify the current vendor documentation.
