Web interface is gone (again)

web interface is gone. When I try to restart it I get

I am not sure how/why incorrect video buffer initialization is preventing the interface to load.

[chchia]

and this is the 4th time for me, CUBE full, and every time this happen, there is no way to recover by just reboot, i need to disassemble the whole CUBE to retrieve the micro sd cad and format, thats the only solution.

and this is 4th time, such an unreliable product considering that it should be designed/used for remote access support.

I ran into a similar issue with my NanoKVM, where the NanoKVM-Server kept crashing during startup due to an invalid resolution (26x11). I managed to fix it by adjusting the resolution values in /kvmapp/kvm like this:

echo 1920 > /kvmapp/kvm/width
echo 1080 > /kvmapp/kvm/height
/etc/init.d/S95nanokvm restart

After that, the NanoKVM-Server started up without any problems. Hopefully, this helps someone facing the same issue!
