Time and again I have seen members complain about trying to initiate a video stream on their N3DS via NTR CFW but receiving the error "A blocking operation was interrupted by a call to WSACancelBlockingCall." This had been an issue for me too, and nowhere online could I find a solution. Until I did it myself.

The issue happens if you're on a Mac using a Parallels Windows VM. You need to change the network settings.

Go to the native OSX menu bar for your VM. Devices > Network > Bridged > WiFi (or Default if you are connected via Ethernet). Parallels has it set to shared rather than bridged by default, and for some reason this interferes with NTR's remoteplay feature.

I don't know if any other computer setups cause this issue. If so, share below.

Hopefully this gets picked up by search engines so that no one else facing this issue is stumped. Mods if the thread title seems ineffective feel free to change it accordingly.

 

im using win 7 and get this

 

I have 2 n3dsxls with LUMA 6.5 (one is a9lh sys11.2.0-35u, other sys9.2 then through menuhax for luma or rei as emu/red11.2.0-35u) and cannot get NTR to work on either. I don't know if I tried it on the sys9.2 through pasta yet but is there a way to get it to work on luma with it 11.2.0-35u?

ridge racer 3d is what i used to use ntr for (for menus set clock to o3ds and gameplay set clockrate n3ds, otherwise it crashes with ntr) always seems to crash with luma if n3ds clockrate enabled. game has framerate drops at o3ds clockrate

https://github.com/Shadowtrance/BootNTR/releases/tag/3.3-3D seems to work with 9.2 pasta and seems to allow cpu config. other versions on ntr wernt working for me anymore. nvm cant get ntr to work on any of my ds anymore, guess ill never play ridge racer 3d again as after playing it on a n3dsxl with no crashes of framerate drops back when luma wasnt even a thing yet was awesome

 

Well for one, on your N3DS with A9LH on 11.2, you need to make sure you do not have a firmware.bin file on your SD card (at the root or in the SD/Luma folder).
Then you need to make sure the option "Enable firms and modules to load from SD" is off.
Then make sure you're using the correct build of NTR booter for 11.2 located here.

As for the other 3DS, you can use the same method as before. If the above doesn't work for you menuhacks 3DS then, try using another build of BootNTR, check the option in Luma, and place a firmware.bin inside your Luma folder on the SD that corresponds to the last working setup. I.E. Use an 11.1 firmware.bin in the Luma folder to run the 11.1 BootNTR on 11.2

 

I've completely disabled the firewall and antivirus, added exceptions to port 8000 in the firewall, added exceptions in the antivirus for nitrostreamer and ntrviewer, and forwarded port 8000 on the router (I think). Nothing works.
