Connection refused with https site

[guillaum...@gmail.com]

Hi,
I've just started to install qz on my computer.
After installing the last Java (8.0.201) i've been able to print with qz on local website and on website which use http.
But when I try qz with an https website (like the demo or others websites) I have an error :
WebSocket connection to 'wss://localhost:8484/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

What did i do wrong ? How can I solve the problems ?

Thanks
Guillaume

Hi,

What browser are you using? Firefox requires a restart after installation for HTTPS to work.

I've tried with both chrome and firefox and it's not working on both

This may be a sign that QZ wasn't installed properly.  Can you run the desktop installer and post the output of it?

Next, can you zip up %appdata%\qz and attach it to this thread?

Hopefully that'll be enough for us to identify the cause.

Thank you really much for the help

No worries, I got them in the previous email.  I'll take a look.

It appears QZ Tray is still running in the background (could be as another user, through Command Prompt, or through an IDE such as IntelliJ).

Can you kill all java processes on the PC, reinstall and see if it fixes it?
