Unable to open image: /files/tools/97d28ffc-da89-407b-a715-d2a417b47c61.png?timestamp=1730708211&nonce=8b613d3ecadba3b5c55437551fa1e40e&sign=WcwxOZiyE58MJpOo9Ze4Wiy3aW7h40iZY0C_ByyvSNw=

Is this because I need to set the env variable FILES_URL ?

I found a similar discussion titled "Unable to open image: /files/tools" which is currently unsolved ^[1].

Regarding your question, the FILES_URL environment variable is indeed important for accessing files in Dify. It serves as a prefix for file preview or download URLs and should be set to an externally accessible address. This ensures that the URLs are correctly displayed on the frontend and can be accessed by multi-modal models. Additionally, image preview URLs are signed and have a validity period of 5 minutes to prevent unauthorized access ^[2][3].

Make sure that the FILES_URL is configured correctly in your environment to resolve the issue with accessing images.

If I am hosting dify at https://dify.example.com, can I also set FILES_URL=https://dify.example.com ?

So both APP_WEB_URL and FILES_URL can be https://dify.example.com ?
