Connection issues after ROCK installation

I installed ROCK on NUC6i5SYH. Since then, it lost connection randomly, which looks like ROCK restart every minute.
Is there anyone who has same problem like me?

I have NUC6i5SYH with 128G SSD, 8G ram and 1TB HDD.

Have you set your BIOS according to the Install Guide? Have you installed the appropriate codecs?

These are the two most common issues.

I set BIOS according to the Install guide twice.
I will set it one more time.

How were you able to tell ROCK restart every minute? From the remote (browser) or from ROCK user control page?

On we control page, running time is reset and on remote, zone setup is deleted after lost connection.

There are 2 running times, which changed?
