Blank screen in browser when starting WinCC Unified runtime

I suspect it has something to do with user management and certificates but I don't have clear solution. This has happened to me before, but I created new project, trasnfered everything, and it solved problem temporarily. Now as commissioning is closing in, I want that problem to be solved for good.

I have seen this as well on my virtual test environment. The trick in these cases was to make my current IP static, run the configurator again and do a full download with all possible resets. Now we are in the live situation, everything is stable.
