Zscaler endpoint fw/av error when I make ms teams calls

Hi! I have a company Laptop with zscaler. When I’m at home I can work fine all day, but I get an odd behavior when I try to do video calls with MS Teams.

Basically, when the call starts, the zscaler connection crashes and I see this error in the zscaler interface: Endpoint fw/av error.

I actual wifi connection doesn’t fall, but I have to do a re-connection in order for zscaler to reconnect. I can then join the ms teams call for a long time. Sometimes, after the initial reconnect, I can be over half an hours in a call only to crash again.

Any ideas? Thanks in advance!
