Hot code push for Webapp does not work sometimes?

This happens on localhost and also on my deployed production server.

Hot code push works great the whole day. When I open the Webapp the next day it doesn’t.
The Webapp server status is connected and all server method calls work but my app stays at the old version.

Any ideas?

Shame on me!

Hot code push worked great.

I used a session var for the code version which was not updated.

Sorry for the spam.
