I cant fix this ping issue

I have stabil 150-166 ms in EU servers in wynncraft. This starded few weeks ago and only happens in wynncraft. I have no internet problem in any other online server for any other game or minecraft. I ve tested almost everything. I cant fix it. I dont know what i should do.

Okay, things i know.

Its not my router, its not my computer, its not dns or anything. I tried change many dns, turning it off/on, firwall settings, deleting mc and install again, withoud mods anything.

people in same room, same router, same mods have no issue about ping its only me.

If is there anyone who can help i would be really happy - thnx

well they dont let me use links to add screenshot of f3, weird rule.
