Packet Loss But Only Affecting Zoom?

[anonymouswaffle]

I have a very good hardwired connection, getting 604.9 mbps down and 641.4 mbps up and 7ms latency when running a speed test on Google. Teams and Slack meetings work fine. With Zoom when I try to share my screen I instantly get the unstable internet connection warning message, and participants report that I am breaking up. I hear and see them just fine, so it seems to largely be an upstream problem and not a downstream problem.

When I run Zoom's network diagnostic tool, in the MTR details, I see that for host IP 68.105.30.114 I am getting extreme packet loss, so I have to assume that is the culprit. If I Google that IP address, it belongs to my ISP. What can I do about this? Is it something I need to bring up with my ISP? Again, I only experience this with Zoom. If I run the packet loss test at https://packetlosstest.com/ set on the Zoom pre-config, I get 0 packet loss.

Any ideas? I am at a loss. Thank you!
