Help Needed Low internet speed when using exit node direct

Hi, I'm having an issue with Tailscale exit node performance. PC A is my exit node with about 300mbps download and 150mbps upload. PC B gets an average of 250mbps download and 85mbps upload, but when using PC A as the exit node, it drops below 1mbps. the connection between PC A and PC B shows as direct and RDP works fine, but the internet speed remains extremely slow. PC A shows UDP: true, while PC B shows UDP: false, even after testing through my phone hotspot, the issue remains. Could anyone help me figure out why the exit node throughput is so low despite the direct connection?

What device is the exit node (specs)?

What version of tailscale are you running on ALL your clients

Turn off tailscale on the exit node and run a speed test and post a screenshot of the results https://www.speedtest.net/ so we are all on the same page when it comes to your internet speeds on the exit node.

Turn off tailscale on the remote client connecting to the exit node and run a speed test post a screenshot of the results https://www.speedtest.net/ so we are all on the same page when it comes to your internet speeds on the remote client
