Can't connect and frequent LD

[Pini]

My isp giving me a solid internet, 35ms / and 15gbit/s stable. I can watch multiple streaming np. Can use internet and it is fast.

But usually i cant play. Well some time i got error at the start, saying me cant connect to server, some other times i dont see servers. I go LD frequently zoning too.
Maybe anyone experiencing the same? MAybe something i must say to isp? cant imagive why EQ should not work great as other app.
