NNinteractive used to work, but with a recent nightly, I am getting this error.

```auto

```

the docker image is running on the same computer. I have tried replacing the address with 0.0.0.0, localhost, 127.0.0.1 as well as the actual IP address. Still getting the same error. There is no output on the docker console (indicating that request reached the server).  
This is on ubuntu 22.04, slicer release 33625.

Same error on using the today’s preview on my Mac, with the same server

Maybe add http:// to localhost in the url

additionally there is a separate bug.

If you do not create a segmentation object before switching to NNInteractive, and try to set create the segmentation using the Segment Editor widget in NNInteractive, Slicer application closes with this error:

```auto
[CRITICAL][Qt] 06.05.2025 04:51:27 [] (unknown:0) - void qMRMLSegmentEditorWidget::setSourceVolumeNode(vtkMRMLNode*) failed: need to set segment editor and segmentation nodes first

```

Himm, that fixed it, but do we really need to specify that?
