Trying to use 2 flashes off camera with remote triggers. The master will trigger the flashes, but the camera D810 with the master on the hotshoe, will not. To start with I went into the custom setting menu, Braketing/flash, flash control for built-in flash, and set it to Commander mode, both Group A and B set to "M", all units set to channel "1" and pressed OK. Still NO joy. I have even tried it without the master on the camera. I have even tried it with the same settings on a D750, and still no joy. So what am I missing, and or doing wrong?

What are the brand of flashes and brand of remote triggers? IR or RF triggers?

Flashes are Neewer, and triggers are also Neewer.

Found this in an article re D810 here, https://wiki.pocketwizard.com/index.php?title=Nikon_D810

Not sure if it is relevant with respect to your Neewers

Flash Sync Speed - Custom Camera Setting
When using a Nikon camera and ControlTL radios, the camera's "Flash Sync Speed" setting must be set to the slower shutter speed of the two "Auto FP" options. This setting can be found in the "Bracketing/Flash" Custom Settings menu.

Thanks works on Auto FP mode.

Godox/flashpoint have two frequency built in the flash like 433mHz what can trigger Nikon flash, pop up flash and godox, too. The 2.4 gHz frequency can be trigger by its godox trigger or godox flash on camera…..
I don’t know how newer set up is.
The green light flash is the master I can put on camera. The orange light is OCF. Maybe this helps

If the flash aren’t at the same frequency it will show a different sign in the top left corner.

I'm not an expert on flash but,
Are your Newwer flashes for Nikon cameras. If you are using a trigger, I would think you wouldn't use the built in flash at all. The hot shoe would tell the trigger when to fire your flashes. I use the pop-up/built in as a trigger for my Nikon flash when desired.
If your 3rd party flashes aren't for Nikon you will need to have one on camera/hot shoe set to Master/Commander & the other set to slave possibly. If using a 3rd party trigger built for your flash, you should be able to control the flash settings from the trigger. If your flashes do not pick up the signal from your trigger, you might need the same brand as your trigger, receivers mounted on the bottom of your flashes. Good luck & hope this helps.

Trigger and flashes are the same brand, and ordered for use with Nikon cameras. Once I set the Master/Commander to sync speed of 250(Auto FP) they worked. Thanks to everybody for your input and help.

When I use my Sony flash as the slave it is works find because I have the flash mounted on a Godox Receiver. The Godox flash works as the Transmitter and is mounted on the cameras hot shoe. Check your flashes and see if the flash you are mounting on the flash attachment is a Transmitter not a Receiver. The instruction sheet should tell you. You may need to purchase a Transmitter which mounts on the flashes hot shoe and the camera on top of it.

I am sorry I can not help you directly because I do not own or use the equipment (make and models) you specified but I can offer you some advice. I have been using multiple flash in-studio and on many location assignments, hand-held candid work, for a very long time.

Firstly, and I don't mean this to be facetious, start from scratch and go over all the instruction manuals that accompanied your gear and make certain they are compatible and dedicated to your camera system. You may want to contact the distributor or vendor for customer support. It may just be a minor glitch in the setup procedure.

You may be doing everything properly but there may be a defect or malfunction in one of the components- the speedlights, the triggering unit etc. Sometimes employing certain settings will negate others.

If you can't get to the bottom of your issue and nobody with actual experience with this gear can solve the problem- here is may further advice and observations.

I have observed, especially lately with all the automation in flash usage, that many photographers spend too much time and effort trying to master overly complex flash exposure control and triggering systems. The features that are supposed to make multiple flash usages easier and more accessible have made it more unnecesserally difficult and complex. Sometimes, the more bells and whistles in a system provide more potential for malfunction.

It may be easier and more efficient to use a simple radio slave system to trigger your off-camera flash and synchronize perfectly with your on-camer fill light and the camera's synchronization circuitry. It is not difficult to establish exposure manually and adjust your lighting ratio by exposing for the off-camera light and varying the fill light power to establish your desired ratio.

In certain kinds of work such as portraiture, event coverage, wedding photography, photojournalism, sports coverage, etc., it is important to make settgs and shoot quickly and efficiently to capture action and expressions. I have noticed many shooters have to endlessly fiddle with gear and become distracted from their subjects. I hope you will be able to streamline your workflow at the camera and solve your issue.
