We're sorry, something went wrong

I just finished installing the yeti-switch and when I tried opening the web page I got the error message - we’re sorry, something went wrong.

I have checked all over the web, but got notihing providing answer or solution to this. Dmitry is there any idea what I am doing wrong? I have tried 2 different releases and got the same issues.

There is no enough info to say anything. Check logs for details.
