nevermind guys , problem is solved if people in the future encounter this
with battlenet : gateway international EUROPE or any other
this is the solution and it worked
Uninstalling
Method 1: You can simply use a gateway editor software that you can download directly either from here or our tools page, it comes with an easy way to revert back to the battle.net gateways. You'll also have to install the latest game client from blizzard's website and upgrade to the latest patch.
Method2: If using the Uninstall.reg fails then you can do it manually: WIN+R will open up the "RUN" dialogue box. Type into this dialogue, "regedit" and press ENTER. This will open up windows "REGISTRY EDITOR." From with regedit, navigate to:
COMPUTER
-> HKEY CURRENT USER
-> SOFTWARE
-> Blizzard Entertainment
-> Diablo II
From the available "keys" in the right panel of the REGISTRY EDITOR (regedit), double-click on "BNETIP" and change the value from "d2.europebattle.net" to "uswest.battle.net" and click OK. Close regedit and launch D2 (which should be already closed before editing the registry).
i hope this would help for some people , appreciated in case people wanted to help i love the community
