microsoft/WSL#4698 (comment)

A simple fix for me was to set MTU to 1350 (same as VPN interface): sudo ifconfig eth0 mtu 1350

Even SSH connections are more stable now.

This solved my issues as well. I am using checkpoint VPN.

to get the MTU value of your VPN run below command for checkpoint, for example :

echo -e "\033[0mNC (No color)"
echo -e "\033[1;37mWHITE\t\033[0;30mBLACK"
echo -e "\033[0;34mBLUE\t\033[1;34mLIGHT_BLUE"
echo -e "\033[0;32mGREEN\t\033[1;32mLIGHT_GREEN"
echo -e "\033[0;36mCYAN\t\033[1;36mLIGHT_CYAN"
echo -e "\033[0;31mRED\t\033[1;31mLIGHT_RED"
echo -e "\033[0;35mPURPLE\t\033[1;35mLIGHT_PURPLE"
echo -e "\033[0;33mYELLOW\t\033[1;33mLIGHT_YELLOW"
echo -e "\033[1;30mGRAY\t\033[0;37mLIGHT_GRAY"
