Any ideas what could cause the error depicted in the attached graphic? I have enabled/disabled svc, upgraded svc, and reset the ASA. I am running 7.2(1) on the 5520. The ssl vpn had been in production for a long time until this error.
One thing you can check is your IP pools configured.. are these configured right on the ASA box ? I hope there are enough IP addresses in the pool for the server to assign ? i had similar issues once, and i figured that the IP pool wasnt giving IP address to the end client.. run some debugs on your ASA and find out the exact issue..
Hope this helps.. do let uus know if this solves ur issue.
