Constant Ping Spikes up and down from 40-60ms to 200-600ms

After the launch of the dawn of the hunt I played through and finished campaign and started doing maps. Since last bugfix patch the game became unplayable all of a sudden. My ping is constantly moving up and down as mentioned in title from 40-60 to upwards of 600ms completely freezing up the game every few seconds. I haven't had this issue in the past and I have also done many other outside of the game tests to see if the issue was related to my internet connection but all those tests came up as usual. I have no clue what the actual cause is but this has basically stopped me from physically being able to play the game since yesterday.

Here is also a packet loss test based on Germany server, which I am playing POE2 using either Milan or Frankfurt servers. Done other types of internet connections tests also and all of them showed standart results so I really have no clue how my game is getting constant ping spikes.
