If it worked before, and you haven't changed anything in OBS Studio, maybe your graphics adapters got swapped around. Did you recently enable your iGPU (the Intel HD Graphics)?

The bold emphasis is mine.

I'm not sure that I'm interpreting this correctly, but I think in this configuration, OBS Studio is trying to use the NVENC encoder on your Intel HD Graphics, which wouldn't work.

Try one of the following at a time (try one or the other, not both):
  • In your streaming settings, try setting "GPU" to 1, which should correspond to your GTX 860M.
    Don't do that. Sometimes I'm an idiot. The GPU setting here should be 0, so that's fine.
  • In your Advanced settings, try changing your Video Adapter to "NVIDIA GeForce GTX 860M" (or whatever it's actually labeled as).
Or, you could try what @H4ndy said and use QuickSync (QSV) on your Intel graphics adapter. Feel free to experiment and use whatever works best for your needs.

As an aside, I'm not sure that CBR at 2100-2500 Kbps is high enough for NVENC, but if it works for you and looks good, go for it!

Ideas? Sure.

What defaulted to your 860? The Advanced setting? The GPU setting? Something else?

Was your iGPU enabled before it stopped working, or did you recently enable it? Do you use your iGPU?

Also, if you try new settings, you should include a new log so that we can see if anything changed.

Try reinstalling the latest drivers from NVIDIA.

Also, it doesn't matter which GPU OBS is running on when it comes to the hardware encoders.

Huh. Odd. Does OBS just ignore the setting and pick whatever seems appropriate?

OBS doesn't pick anything, it just uses what is provided by the drivers.

Also the GPU setting should not be changed to 1, that should be set to 0.

Wait... okay, I think I get it now. I'm tired, so it took me a bit. I think in your first reply you were talking about the Video Adapter setting, but here you're talking about the NVENC GPU setting. After reviewing the thread again and looking up a few more things, you're right: the GPU setting in this case should be 0, as there is only one NVENC capable GPU here (the GTX 860M).
