Photoshop Generative Fill not working with Ethernet connection at full speed but works with wifi ?

Yes this is exteremely odd. Sorry I couldn't be of more help!

Windows Defender was turned completely off and put out of loop for a test and still no go ethernet generative fill.

So stumped.

I would still check your Windows Defender settings to confirm Adobe, Firefly and Photoshop are white listed.

no i do not, internet work great at 800mbps on ethernet, just no go on and service connect error on generative fill.  Just did a factory reset on router to see if it would help. No help.  Have also rolled back photoshop and reinstalled then updated. No go. Waiting on Adobe senior support to call, but you know how that can go.

@steve yasin do you get any kind of error message while on Ethernet?

Yes, it's the same network. Hope someone can suggest a solution. 

@steve yasin is this connecting to the same network on WiFi and Ethernet?
