For some reason, starting today, none of my users are able to download their AnyConnect client from the VPN Portal. When a user types in his or her credentials, the log on completes successfully, but instead of redirecting them to download the client, they are redirected back to the login page. This also causes the account to remain "connected" as a clientless SSL VPN user. I don't have clientless VPN access set up, only through AnyConnect, the portal is only used to download the client.
Users that already have the client installed can connect without issue, the only issue is with the portal. How can I resolve this?
