Hey Oz Sarkut
 
If you run the pages through the mobile friendly test, there's a lot of 499 errors printed out at the top of the page:
 
 
 
Error like strings can trip the soft 404 mechanism into thinking this is actually an error page with a 200 status.
 
I'd work on eliminating them, (perhaps log them to the console if they are needed for diagnostics?)  and see if the URLs start getting indexed again.
