base64 images not loaded

Hello
i'm experiencing trouble when trying to render into pdf any base64 image
i tried several, even in the online sandbox page (https://sandbox.openhtmltopdf.com/), posting the code:

```

```

nothing get rendered, here the logs:

```

Isn't that supposed to work?

p.s. i read from another issue that it isn't supposed to work on the sandbox, problem is is not working on our java app neither, is there any additional configuration to do ?

Thank you for any assistance
