Searching for “expecting SSH2_MSG_KEX_ECDH_REPLY” in Google lead me to this solution :
Change the MTU of the VPN interface doing so : sudo ip li set mtu 1200 dev your_interface
If you type “ip a” in your terminal, you’ll see the list of all your network interfaces. mtu should be set by default at 1500, try lowering it down and see what happens.
