Eduroam doesn't work on Valo

Hello, I'm staying in Italy for 6 months, i have student-based wifi connections in my dorm but none of them works for valorant. When I try to play the game, this error comes up. Do you know any tricks to solve this? I tried changing dns but it didn't work.

Please help me I want to play with my friends and when I try to play with my mobile data, I get 100 ms
