Anyconnect on Windows 10 fails to connect

[Tony_MN]

Hi, I have searched this plenty nothing seems to solve.

Been trying to create anyconnect network. Cannot seem to get beyond clicking connect with Windows 10 pc's. 

I'm using anyconnect 4.6.03049 on Windows 10.0.18363 and two other win 10 pc's, I have tried the same anyconnect on windows 7 pc works fine. Also works fine from Android phone.

I have tried different anyconnect versions but nothing working. I click connect button and the router debug webvpn output gives "WV: sslvpn process rcvd context queue event"  then nothing more. PC fails to connect.

Router output: 

"*May 7 18:24:35.445: WV: sslvpn process rcvd context queue event"

PC: 

"Connection attempt failed. Please try again."

What do i need do? 

Thank you

Hello,

not sure what you have already tried, but did you try and run AnyConnect in compatibility mode (right click the AnyConnect icon, go to Properties and then select the Compatibility tab) ?

Yes sir. I have tried compatible modes, i have tried most anything i've come across for windows 10 fixes.

I'm obviously doing it wrong. I even tried to go through everything and take it out of registry and anything left over....

I cannot seem to get it all though. Everytime i reinstall it holds on to one ip address i was using for a different router setup i was trying. So thats how i know im not getting everything deleted.

It just gets me that i cant yet figure a way or work around besides thinking of downgrading the OS to Windows 8.

Hello,

which router (and IOS version) are you using as the headend ? It looks like you have tried about everything...the only thing I can think of is to double check if you followed the steps to install the client package on the router correctly:

Hello,

I looked around some more, can you check the below:

On your computer, go to Run --> services.msc, and make sure the 'Cryptographic Services' service is set to 'Log On As' Network Service...

Thank you Georg. I took your last link and started with a wiped-fresh router config. Went through all the steps on a 2901 router. I also took all the anyconnect files to load on it with version 4.6 from the links on firewall.cx

It is finally working now on pc and phone. Thank you for some guidance. I figured it must have been the router setup.

I have a few more things to tweak, I'll check in with a new post or sometime soon.

So yes answer is take everything you have learned and start over following directions, also I had partial working setups that i could look at line by line with split screens for validation.
