fast blue flashing

[joostdejonge]

Dear all,

I just replaced my cloud based homematic with a CCU3 unit.

It does not work completely as I would expect.

The webpage can sometimes be accessed, sometimes it cannot (via ip address).

The blue light start flashing fast, and then it stops.

I can always ping to the device, so it looks like network connections are up.

Any ideas?

Thanks

Blue flashing means no internet connection to update e.g. time and date ..

I know...

It is a strange problem, when I ssh to the device I can sometimes ping other devices, or internet addresses, sometimes I cannot. But the SSH connection is stable...

problems seems to be solved, dhcp was not configured properly
