While I have not heard from any others that are on other versions of windows, However on windows 11 I do know that the latest version of Google Chrome has brought on some issues regarding loading the site properly. The current version is forcing https redirection from the http domain name that the entrance pages are setup to use. The last time I tried using https on the entrance pages it brought a lot of other issues with loading into the chat rooms. I have done some research and found two things that can be tried.
If you are experiencing this issue you can try the following.
In the address portion of the browse place in
chrome://flags/#https-upgrades
At the very top it has HTTPS Upgrades, You will need to select "disabled" and save, close the browser down and relaunch it. Another alternative suggestion is by placing in.
chrome://net-internals/#hsts
Scroll down to "Delete domain security policies" and enter starlightchat.com and chat.starlightchat.com that you don't want automatic redirection. Then click the Delete button.
