P: Generative fill could not be used due to connection

I use ESET internet security and even disable the firewall still get the same results. 

Firewall on windows are "off" message on windows says is using ESET firewall  

Anyway thanks let's see from the good people from Adobe but, yup gonna ask to ESET if I have to change anything on the firewall although is on interactive mode so it allways ask if I let the service connect and if so if I want to creat a rule that allows, witch I say Yes let it  connect allways from now without ask 

@Nexus 6 check your router settings - they may not have changed but requirements may have. See the answer above and confirm the settings.

The generative fill box is greyed out, even with an active selection, but when I try to use Select Subject or any tool that "connects" to Adobe's servers I get the message that due to connection problems, the selection will be made on device.
I haven't changed my operator for my web / TV services, Router is tha same for 3 years now.

When the version of photoshop came out where the image of Iceland with a house was provided for us to test the generative fill everything worked fine. Now I can't use these functions in both versions

@alejandra30106612zaln its pretty telling that it fails less frequently with different WiFi settings. That means its not the Adobe software. I would still check Windows Defender and make sure Adobe Photoshop is listed and allowed. Disabling altogether should have worked as well, but there are various factors when it comes to routers and WiFi - speed, signal strength, consistency in connections, etc.

llevo tress dias con mi compañia internet y me aseguran que no hay saltos en el wifi y señal correcta ...he entrado a configuracion router y he desactivado firewall pero sigue el problema ... falla relleno genrativo saliendo mensaje de wifi ... sin embargo si me conecto a traves de 5 G falla menos ... alguna idea  mas para  cambiar configuracion router de manera que se pudiera solucionar ??? 

To echo @Kevin Stohlmeyer when did this issue start, is it new in the last week/s, what else has changed on your machines/internet? We are not seeing a huge uptick in this issue so it is possible it is a machine/router/internet change outside of Ps.

Do you have the same issue with Ps release, or other Adobe apps?

Thanks,

@kiunnal @alejandra30106612zaln this specific message is factual - meaning you either have very poor internet speeds or your firewall on your router @alejandra30106612zaln this includes Macs is blocking Adobe Photoshop. Connect to the router and confirm that this is allowed.

holaaaa...tengo desde hace mas de una semana problemas con internet en ese mensaje y el relleno generativo ...tengo firewall desactivado y NO USO WINDOWS SINO MAC .... he revisado internet , cambiado cables ethernet y llamdo a mi compañia ...todo correcto pero sigue saliendo mensaje y no hay manera funcione relleno generativo ... y tambien he reinstalado photoshop ..... no se que mas hacer ...ayuda porfa

I believe I did. And it still not working. I even did the refreshed it in the windows defender. Don't see adobe pop up in the windows icon anymore after I refreshed it yesterday too. I don't know what's going to happen today when I use in photoshop. But like I said im still having problems. 

@kiunnal did you check your Windows Defender firewall settings per the accepted answers above?
