My work replaced my old windows 10 laptop with a new Windows 11 one and Zscaler download speeds are currently being throttled by my Deco mesh network of X55's from 400-500mb/s to 4-5mb/s. Upload is being throttled from 500-600mb/s to 100mb/s, although sometimes it's totally blocked.

I've connected through a different network, used a router to test my own connection, disabled Zscaler and tested the connection to the laptop and they all work fine. The problem is solely when using the Zscaler VPN and the Deco network. 

Any idea if there is a fix?
