Algo: Fix for windows 10 VPN connection problems "parameter is incorrect" error

[alexmelSC]

Hi,

Solved this issue myself but saw no mention on here.

I recently moved to a new server where I have Algo VPN but kept getting a weird error "parameter is incorrect" when connection to it.

SOLUTION:

If you install the Windows 10 ps1 file (as noted in the installation instructions) and when you try to connect is says "parameter is incorrect" then so the following:

1. Clear the Networking caches

Run windows cmd window (click windows start menu, type 'cmd', right click on 'Command Prompt' and select "Run as Administrator").

type command below
netsh int ip reset

then type
netsh int ipv6 reset

then type
netsh winsock reset

Restart your computer.

1. Reset Device Manager adaptors

   Open Device Manager
   Find Network Adapters
   Uninstall WAN Miniport drivers (IKEv2, IP, IPv6, etc)
   Click Action > Scan for hardware changes
   The adapters you just uninstalled should come back

The VPN connection then works.

Hope this helps someone.

It works but is there an easier fix? I don't like to do this on all my machines
What causes this issue?

Parameter Incorrect is a problem I have and followed the fix instructions.Still getting the same message and starting to come to the conclusion that there is a corrupt file on the system.Any ideas from any one who has been tormented from this would be greatly appreciated. In the meantime good luck and keep up the brilliant work.Kind regards to you all.

First problem I meet is modem problem. I first click the "reset network" in Setting -> Network and then restart PC, but problem turn to same with you(Parameter Incorrect). Then I tried this solution, after 1st step, the problem still occur. But after 2nd step the problem finally resolved.

Thank you! I had many troubles post KB4557957 (Windows 10 v 2004) & one of them was connecting to work VPN on IKEV2. Man, don't have words to appreciate your tip. I'm a developer, got three different database technologies, half dozen development tools installed and configured...and was going to format the goddamn thing & landed on your solution!
