WhatsApp is not connecting to Internet

Hello

I am having a trouble connecting to my WhatsApp with homeWifi and cellular data as well.

Recently I have been updated to new iOS 15.0.1 and I am using XS max.

I tried turn on/off local network still no results,

since one day I can’t connect to WhatsApp nor with cellular data nor with wifi .

But I have good internet for other apps like YouTube and google surfing. Only WhatsApp is not working .

help would be appreciated

thank you
