Sending simple message from website

[jdlaw75]

I have an ASP.NET website which needs to sometimes instigate a print job, which is provided by a VB.Net application always running on the same server. The XDMessaging trigger is working on that app.
Sending the message from the VS2019 development environment works brilliantly, but when triggered from the website on a another device, the message never seems to be getting through.
Any thoughts?

Further to my earlier post, I have ascertained that, whilst the messaging works within the VS2019 environment, it fails when running under the only browser on the Windows 2016 Essential server (Internet Explorer).
Of course, it does not woirk on any browser running on another device either!
