We've been having an issue where users are getting disconnected from vpn everyday sharlpy at 02:30 AM. We have two ASA's but this issue is happening with only one of them. Also we do have a call center which is open 24/7 and during this time the agents are getting international calls. Please if anyone has any idea why, let me know.
Further to what Raj has requested, let me know if we're authenticating these users via any external authentication server like ACS or NPS. If yes, I'd also like to see if there is any "time & date" based condition configured for this specific user.
Since this has been an ongoing issue that occurs sharply at 2:30 AM, I've increased the logging buffer to get any user output(since all users are getting kicked out) and will post it here for you most likely tomorrow morning.
