Openhab web gui not working anymore

Hello,

I use openhab for a few weeks now (1.8 snapshot).

Hardware: Cubietruck with SSD and Armbian 4.81

Since yesterday the web interface is not reachable anymore. I did not change anything so I have no clue what this could be.
Also tried a clean setup of openhab (1.8 without addons or config), same issue.

The log shows this periodically:

IP 192.168.0.216 is my workstation and 192.168.0.3 is the cubietruck

Any idea what’s happening ?

Thanks

Okay, I found a similar issue here:

My Browser is Chrome 47 on Win10

I opened tthe openhab url in Chrome private mode and IE11 and it works, so it looks like my browser cookies are messed up.
Strangely my sitemap is empty, I have to check why. edit: found it, Did an update to 1.8 and ran into the Slider Bug in Classic UI
