Hello! I'm sorry you're experiencing this, I can imagine how frustrating this would be. The game itself is unlikely to be shutting down your computer or disconnecting your internet, that's typically outside what a website can directly cause. There may be something within your browser, device, or network that may be contributing to this occurrence.
What generally causes a device to close unexpectedly are issues such as corrupted cache files, outdated cookies, an outdated browser, or a browser extension interfering with the game. Security software can also play a role, antivirus programs, firewall settings, ad blockers, and privacy extensions may sometimes disrupt a single games ability to function.
Browser games can also stress system resources differently than casual website browsing. If there are underlying issues such as available memory, outdated graphics drivers, hardware issues a specific game may be the one that exposes those problems and can cause browser crashes and full shutdowns.
Lastly, being knocked completely offline should not be occurring. Modems and routers need periodic maintenance and firmware updates. Network equipment that's overdue for an update can at times contribute to connection-related issues as well. I developed a guide on this after another player was experiencing issues.
Please take a moment to review the guide below that matches your device for detailed assistance:
