I am also having this same issue with BF4 on EA app on PC (windows 11).
Every time I join any server I am kicked saying "you have lost connection to the server" after about 10 seconds. Tried for a week now, problems started around 17 Feb.
I have tried restarting my PC, reinstalling punkbuster, trying different servers and all obvious things to no avail.
I am located in London, UK and have tried UK and German BF4 servers.
Nothing wrong with my internet connection and BF5 has been working fine the whole time.
EA please fix this, BF4 servers are broken.
