 **Note**: Using Docker is recommended as it simplifies the setup process, especially for managing environment variables and dependencies.
 
+#### Ollama connection errors
+
+If you're facing an Ollama connection error, it is often related to the backend not being able to connect to Ollama's API. How can you fix it? You can fix it by updating your Ollama API URL in the settings menu to the following:
+
+On Windows: `http://host.docker.internal:11434`<br>
+On Mac: `http://host.docker.internal:11434`<br>
+On Linux: `http://private_ip_of_computer_hosting_ollama:11434`
+
+You need to edit the ports accordingly.
