Suddenly Very slow Downloads and Uploads speeds from my proxmox server

For some reason I noticed from yesterday my proxmox host, and all of my VMs and LXC containers are running at like 200 KB/s Dowload/Upload to the internet (my internet connection is 1Gbps up and down) but for LAN I get my full 2.5Gbps link speed when transferring files to other computers, and my other devices on the same switch get the correct full speed. Not sure whats going on here.

Tried Rebooting, now Updating my packages, but its taking ages with this weired speed-down.

I have tested downloading a Linux ISO via torrent in one of my VMs, and that was speeding 17MB/s and above, but anything else I could think of was locked at 200KB/s

Maybe this is an indicator, This is my TrueNAS VM, and x.x.x.200 is my proxmox host

Any ideas would be appriciated.
