Extreme ping Issues in the evening

Hello world! I want to apologize in advance for my English, I use an online translator. So, my problem: Since the Wynncraft 2.0 update, EVERY evening (around 12:30 utc) incredibly high ping (100k+). My friend, who lives not so far away (1500 km), has no such problems. Regardless of the in-game servers, the ping does not change. I usually connect to EU servers, but the others work well too. In the daytime, a stable ping of 70 ms. On other servers, there are never any problems with ping. What can be done about it? Thank you in advance for any help! :)
