Lag on Nexus King

Hi all, looking for help in figuring out what on earth is creating such high latency spikes on Nexus King mythic prog fight. I’ve now encountered the same issue on two weeks in a row. After progging 1 hour or so, I start to get major latency spikes taking my somewhat okish 35-40ms to 2500ms or more. I do not understand what is causing this.

I monitored this with a ping plotter. and I got huge constant spikes while WoW was on and then it stabilized after I closed the program.

I have 1000mb internet connection and Mac Studio M4 with latest OS26. The game runs otherwise smoothly without issues.

Anyone have any guidance how to approach solving this?
