For a few days now we have experienced some problems with the SSL-VPN 200 device.
Everything is generally working, the firmware is the latest available, nothing has changed in the setup, with the internet connection or otherwise, but the device keeps becoming unresponsive, meaning when you try to access the Virtual Office website via https://www.domain.com:4433 it doesn't load and errors with with "cannot find website".
The only way to resolve this is to do a manual reboot on the device and it will work OK again.
We have also contacted the ISP to make sure nothing is suddenly blocked, or otherwise impaired their end, and they have confirmed all is well and were able to see all devices connected.
We only have two of those devices still in operation, but it would be good not having to do any replacements, especially on top of Christmas.
Has anyone experienced this and/or resolved this kind of behavior before?
