Thank you for your reply.

We would like to know whether you built the virtual machine on Hyper-V? Or other third-party platforms?

If you are using Hyper-V, based on your description, we recommend that you try the following solutions.

To disable Jumbo Frames on a Hyper-V virtual switch, you’ll need to adjust the MTU (Maximum Transmission Unit) settings. Here’s a step-by-step guide:

1. Open PowerShell as Administrator.
2. Identify the Virtual Switch: Use the following command to list all virtual switches and their properties: Get-VMSwitch
3. Disable Jumbo Frames: Set the MTU to the default value (usually 1500 bytes) for the virtual switch. Replace SwitchName with the name of your virtual switch: Set-VMSwitch -Name "SwitchName" -NetAdapterInterfaceDescription "Ethernet" -NetAdapterAdvancedProperty @{"*JumboPacket"="1500"}
4. Verify the Change: Confirm the MTU setting has been updated: Get-NetAdapterAdvancedProperty -Name "vEthernet (SwitchName)" -DisplayName "Jumbo Packet"
