Massive lags on server in late hours (Not FPS)

So I have problems with ping on Wynncraft. I Play in the European region (Poland) I use the eu.wynncraft.com IP but it doesn't do anything. The problems are starting at 3 PM before 3 PM everything is fine and I can play the server. And after 3 PM there are massive lags that can't even play. My character lags so much that I can't even walk properly and boost myself because I'm being pushed back like there was a DDoS attack on the server. Is there a fix to that? Or this is totally server side and i can't do anything with that. I'm asking because theres school and my friends can't play in the early hours so they cant even play properly without lags.

 

Use Ethernet? Im in france and i use play.wynncraft.com, i dont have these problems tho

 

I have ethernet cable.

 

its most likely proxy issue, you should try using vpn to join via different proxy

 

same, i came back after almost a year and now my ping wont go below 600 like how am i suppose to play also i do play hypixel and other servers where my ping is 200-300

 

I'm also from Poland and when I swithed to new version I had like 20-30 fps. Then I installed the lunchy made by Kmaxi (youtuber) and my fps rise to 70 on avarge - try it
