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.

came across this in a search and realized i didn't post the solution.

I discovered that if, during development, I have several browser tabs open, usually across several apps ON THE SAME HOST (ex. I have 1 aware server, with many BSVs running on it), if in the case of doing lots of things across tabs, if one of those gets a popup alert "the app has been updated", then it has a chance to "appear to hang" a login on another tab (which is on the same server).

When you try to login to a BSV, as it says in the OP, it just hangs. You don't know why... because you are not aware that in another tab, it has a dialog box awaiting a reply.

So if this happens, you don't need to just "close everything" out of frustration. Search your windows & tabs until you find that dialog box, and by the time you get back to your original window, you'll already be logged in.
