Unable to connect to Server from Android Device

[yondu]

My SoftEther VPN Server is running on Windows Home Server 16 and accessible from a Windows 10 Client via SoftEther VPN Client Manager. I also want to connect Android-Devices, but somehow it shows "connecting..." for some time and then "not successfull" in Android settings.

Here some information about the settings on Android:

• Name: VPN
  Type: L2TP/IPSec PSK
  Server Address: DDNS-Adress
  L2TP-Key: blank
  IPSec Identifier: blank
  IPSec Pre-Shared Key: set as on server
  Username: Clientname@VPN
  Password: set as on server

Here some information about the settings on the server:

• Virtual Hub Name: VPN
  L2TP over IPsec enabled
  Raw L2TP with No Encryptions enabled

I would appreciate any help. If my post lacks information, don't hesitate to tell me what I should post.

have you found an answer? if not, use https protocol on port 443, it penetrates everywhere

do not use L2TP/IPSec PSK - this is blocked by stupidiest router everywhere

For L2TP/IPSec to work you need to open/(port forward) UDP ports 4500 & 500 to the machine running the softether "server" software.

you said" Raw L2TP with No Encryptions enabled" I would enable the encryption options

Look at the bottom of this page for port info: https://www.softether.org/4-docs/2-howt ... VPN_Server
