i have over 500 ping on poe2

I have checked everything about my internet, and it's good in everything except Poe2, which has a high average ping reaching 2k ping. idk what to do. I play from Steam on EU servers like (Paris, Milan, Frankfurt) , I always check the server before I enter, and server connection says I have 50-55 ping in this server, but when I log into server, I found it over 2k ping
