qz-tray connection closed

[vijsh...@gmail.com]

Hi,

I'm using QZ with angular first time. I want to print a pdf file, It first established qz connection but suddenly application closes the connection with qz-tray.

Chrome browser console output(qz-log:):
Established connection with QZ Tray on ws://localhost:8182
Closed connection with QZ Tray

What should I do to make this right?

The cause could be many things. I recommend you close QZ Tray and restart it from console to find out what the underlying cause is and address the exact error that appears in the Java backtrace. 

You may attach the logs here as well.  Please review for sensitive information before attaching.

The logs are located in %appdata%\qz on Windows.  Or Tray, Advanced, View Logs, Open Log location.

Any Suggestions?

Thanks in advance!!

Can you close out all instances of QZ Tray and try again?  The "address already in use" means you were spawning a second instance, which doesn't have the information we would need for troubleshooting.
