We have an issue where the new printer option in Canvas is working in our dev area (non-https), but is not working in our stage and production environments (https). The http vs https is the only difference between the environments we can think of. We have opened the same ports to let it work on all three servers. Any thoughts on how to get around this?
Thank you,
Chet
Hi @chet_watkins,
What is the behaviour of the situation? Any errors on the application.log file? Is the same URL, accessible within the server itself? For example, if you access it via https://stage.server.com/finance on your PC, is this same URL accessible when you open it on a browser within the server itself?
You can go into < CWAS >\printer folder, and open up the chrome.exe file there. It will open up the browser in a non-headless mode. Does the URL open from there?
One of our applications in production having a valid SSL certificate is using https and printing is working in there. We have tested it before with a development/personal certificate too so it should not be an issue as well.

Yes, the friendly URL we have for stage and production canvas is accessible from Chrome on the respective servers themselves.
According to the logs, it is trying to use https - “2018-09-05 14:31:30 com.cubewise.h DEBUG ChromiumPrinter:130 GetResponse URL: https://localhost:9004/json/version”
But if I open chromium using the parameters in the log using non-headless mode,
D:\CWAS\printer\chrome.exe --remote-debugging-port=9007 --disable-gpu --window-size=1920,1080 --allow-running-insecure-content --hide-scrollbars --proxy-bypass-list=* --proxy-server=‘direct://’
https://localhost:9004/json/version gives a site cannot be reached error.
If I enter http://localhost:9004/json/version it works fine.

Just to add, I have tried this with setting the printer url in the settings file to https and http. Here are the logs for http. The same errors with the http/https on the localhost being the only difference.

Hi @chet_watkins,
Thanks again for posting the logs. We might have encountered something similar to this from before already. We will contact your local Cubewise office and arrange for you a build with a number of loggers and printing optimizations included so we can further verify, if not resolve, the issue.

Cheers!

The printer issue is also happening with me as well and the thing is that it is not getting connected and it is not being accessed through HTTP formats. It is showing Epson printer error code e-01 also.
Hi @jonsnsow1221,
Which version of Canvas are you using?
If you are not using the latest version, we would highly recommend that you upgrade to the latest first.
There have been lots of optimizations since the prior releases.
https://forum.cubewise.com/t/release-canvas-v3-2-0/2448
Let us know how it goes.

Cheers,
