Lag spikes that freeze the game do not go down again

Since a few weeks poe2 started to have very terribly lag spikes and even game freezes related to lags (ping keeps going up and never going down again thus i have to restart). I thought it may be my internet but i do not have this issue in any other game and additionally if i just restart the game everything is fine again (until the next spike in probably 20min...). Since i play on console i only tried to reinstall the game but it did not change anything. Does anyone have a similiar problem? or has any ideas how to fix the issue?
