v9. Some users report 'hang' after login. blank screen

[Jaymer]

Had a weird thing start happening this week - this is not a "normal" v9 issue. v9 has been working fine.
Chrome users (they would try Edge when Chrome started failing - same thing) would get HTML login screen, but after clicking Login would not see their VP. System appears to hang.

I would watch the Tomcat Output on the server and the Login would hang... not all of the normal lines showed up in the Output.

Exit out of Chrome and try again and it would proceed as normal.

Any ideas?

Of course, the bootstrap file IS there, and its always shown that theme error message, so its not been a problem.
but if you're reading this, can you check your Tomcat Output on v9 and see if you see a similar message?
Maybe something incorrect on Vlad's side.
