We have VPN concentrator 3030 with software version 4.7.2.J. We use to manage it through GUI by using HTTPS access. The problem, now, is that we are not able to HTTPS (on private interface) it to manage the concentrator through GUI. Though, the device can be telneted at port 443, and is also accessible through telnet. We have also rebooted the device twice.
Is this some sort of BUG or something got misconfigured?
Here's some information for you on this issue. I'm thinking you have to re-generate the certificate on the concentrator. HTH
