Hi Mike,   Compliments of the season to you. So I have found another work-around which might be easier to apply from a GPO level instead.   https://community.cisco.com/t5/vpn/authentication-failed-due-to-problem-navigating-to-the-single/td-p/4754972   I simply added these registry keys (no reboot) and it worked! reg add "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Cisco\Cisco AnyConnect Secure Mobility Client" /v UseLegacyEmbeddedBrowser /t REG_DWORD /d 1 /f reg add "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Cisco\Cisco Secure Client" /v UseLegacyEmbeddedBrowser /t REG_DWORD /d 1 /f PS. Run these as Admin. Best regards, -DawieKabouter- ... View more

Hi Mike,   Thanks for getting back to me. I'm glad it worked, however, I wish to further update you on this case. It turns out my own solution was short-lived.   I had to add the domain user to the Power Users group and now the user is able to connect consistently without this erorr. I would suggest to monitor this, if the work-around is no longer working, try adding the user with different permissions on the local system. In this case I know for a fact Power Users group works.   Kind regards, -DawieKabouter- ... View more

Hi Mike, perfect. Just to be clear make sure whoever do the work-around to be logged on as a local admin. Installing the software as admin is not enough.   Good luck!   Regards, -DawieKabouter- ... View more

Hi Mike,   I have the same issue and Meraki support referred me to Cisco TAC for further assistance. Since you've already done that there is no need for me to go through the same process.   HOWEVER, while being on the phone with Meraki support I sort of fixed the issue for myself. At least for now on only 1 PC and yet to test it on others.   My scenario explained below; - I found that local admin users have no problem connecting and no warning. SAML auth works. - When a non-admin user tries to connect, the error appear. - I logged in on the troubled PC as admin user, open AnyConnect and entered the hostname. Connected and voila!  - Logged back in as the non-admin user, opened AnyConnect, enter hostname address and voila!   Don't ask me why and unfortunately I can't confirm if this is a working  work-around on this issue. I will test it on more troubled PC's and confirm back here.   Good luck if anyone want to try this work-around in the meantime.   -DawieKabouter- ... View more
