Thanks for the quick response - it's not a server issue, it's a client one. I can play the game just fine if I load the game I made in Chrome (even in an anonymous window). The issue is when I try to play it on my Google Hub (it's like an Echo Show, but from Google rather than Amazon)
The "web browser" equivalent in a Google Hub will only render certain simple web page. It does support HTML5 and WebGL, and can for example render games made with Phaser, GDevelop and some simple ones from PlayCanvas, but I can't get it to render my tutorial implementation made with Construct 3.
Some restrictions on Google Hub include that you cannot open any modals or popups, and you can not access the WebStorage API. I strongly suspect that the initial issue I'm running into is related to the web worker trying to open a popup window or something similar, but I'm having trouble modifying the bootstrap to bypass that. What I really need is to be able to radically simplify the bootstrap and keep it to just the basics of the game and display.
Is there a very simple export option somewhere? Or an export option that makes it easy for me to strip out any extra bootstrap and keep just the basics? I'm a new user and have not wanted to pay $100 only to find out that this won't work (so I can't play with all the export options myself).
I'm happy to pay for a year license if it works - of all the engines I tried yesterday, this one was really easy to use. However - if I can't output a stripped down, simplified game that I can easily host and run anywhere, then that somewhat defeats the purpose for me.
