[Ultimaker 3 camera stream missing]

My camera stream has stopped working with one of the recent firmware updates. I can ask the printer where to look for the stream at the following URI:

http://10.37.10.59/api/v1/camera

And it tells me:

{"feed": "http://10.37.10.59:8080/?action=stream"}

However, trying to connect to this port gets me a connection refused message.

Is there some service that has failed to start, or did the URI for the stream change?

[Multi-color prints using Cura 2]

I'm trying to print a multi-color print with my Ultimaker 3 extended, using Cura 2.3.1 on Windows. I've designed the 3 parts using OnShape, and downloaded them as separate STL files. I can load and see the STL files, and set the print core and material type for each part. When I try to merge the 3 parts, the main part shows up in the correct location, and one of the sub-parts drops in where it should. The second sub-part comes in at the same location as the first sub-part.

I've uploaded the STL files and some screenshots to Thingiverse:

I can manually move the bolt 2 to the right location, but is there a better way?
