I have a ASA5510, 50 WebVPN User License, currently configured for WebVPN and only serving 4 Intranetlinks, nothing more. Everything works great, but after 2 or 3 weeks it hangs. I can login, but when I want to use the OWA link, it says the server is unavailable. Pressing the Backbutton brings me to main menu and other links work. After logging out from WebVPN I can't login again. It hangs while loading the certificate (it's an own one, but not selfsigned from the ASA). I can connect through SSH (so SSL should work), but I can't connect with ASDM.
I turned on debugging everything about crypto, http and webvpn, but there was no error.
