Q: problem with installing win10 on mac el captain

Can you the following trace route commands?

traceroute  swscan.apple.com

traceroute  swquery.apple.com

traceroute  swdownload.apple.com

traceroute  swcdn.apple.com

Can you download and test with Brigadier - https://github.com/timsutton/brigadier ? If you need help with syntax, please see the following example.

MyName-rmbp:brigadier-master MyName$ ./brigadier -h

Usage: brigadier [options]

 

Options:

  -h, --help            show this help message and exit

  -m MODEL, --model=MODEL

                        System model identifier to use (otherwise this

                        machine's model is used). This can be specified

                        multiple times to download multiple models in a single

                        run.

  -i, --install         After the installer is downloaded, perform the install

                        automatically. Can be used on Windows only.

  -o OUTPUT_DIR, --output-dir=OUTPUT_DIR

                        Base path where the installer files will be extracted

                        into a folder named after the product, ie.

                        'BootCamp-041-1234'. Uses the current directory if

                        this option is omitted.

  -k, --keep-files      Keep the files that were downloaded/extracted. Useful

                        only with the '--install' option on Windows.

  -p PRODUCT_ID, --product-id=PRODUCT_ID

                        Specify an exact product ID to download (ie.

                        '031-0787'), currently useful only for cases where a

                        model has multiple BootCamp ESDs available and is not

                        downloading the desired version according to the post

                        date.

The socket.error Operation Timed out indicates network issues between your Mac and the Apple servers. This is also causing your BC Assistant software download issues. Are you using a wireless network connection?

Can you test using Brigadier using a cable?

Brigadier does not use the URLs from the command line. If you notice, it is using the same one - http://swcdn.apple.com . You seem to have intermittent connectivity. Since Brigadier completed, can you try BC Assistant and try to install Windows?

Is it possible to move the Mac to a different physical location and using a different network?
