Hello.

Can you log in normally in anyconnect client?

Can you share screen with your setting?

[MHM Cisco World]

please do this and check
device manager > network adapter 
select the network adapter and right click update the adapter 
restart the PC.

[AbdullS]

Thank you for your response.

I have went to network adapters and updated all of them one by one and restarted PC.

Same issue.

[MHM Cisco World]

same network adapter for any connect, right click select properties and unclick IPv6.
try this way.

[AbdullS]

If I try to do that and test it will automatically revert to checked.

If I open properties for cisco anyconnect secure mobility client connection from adapter settings in network and sharing center I get this.

[MHM Cisco World]

just unclick for IPv6 
and see if the anyconenct is connect or not

[AbdullS]

Thank you for your response.

When I uncheck IPV6 and try again it doesn't work.

And when I go back to check I find it checked.

I think when cisco anyconnect fails to activate the adapter and then attempts to repair it reverts back to it's original state (checked)

I hope this way is not re click again.
