rmcl error

When I try to mount my Remarkable, it produces the following errors:

```
rmfuse ~/Remarkable -v
INFO:rmfuse.fuse:Mounting on ~/Remarkable
ERROR:rmcl.api:Failed to decode JSON from bytearray(b'')
ERROR:rmcl.api:Response code: 401
INFO:llfuse:handler raised <class 'rmcl.exceptions.ApiError'> exception (Failed to decode JSON data), terminating main loop.
```
