Microsoft Teams calls Temporally disconnect only on Xfinity network

I'm experiencing ongoing issues with my internet connection during Microsoft Teams calls. Whenever I am on Microsoft Teams, I'll be on the call and suddenly get the message "hold on, we're trying to reconnect you" it only lasts a few seconds but enough to miss people speaking.

It happens both on and off VPN. The issue does not occur when I hotspot or connect and use Microsoft Teams on another provider's network. I've followed the troubleshooting steps multiple times, including restarting the modem and laptop. How can I resolve this issue?
