Looks like Ucanet is aware of the issue and is working to get it resolved, so that's really good. I will be able to see my retro site on my retro PC in no time!

That said, I already KINDA can?! I found out about Browservice today, which is a remote rendering service that allows websites to render on my modern PC, and then send interactive screenshots to my retro PC. My retro PC then sends keystrokes and clicks back to it. It effectively enables me to interact with the modern internet on my retro PC!

I can almost daily driver this thing now. I can access Telegram and Discord right through Browservice, and other than it having 2-3 FPS, it's completely fine! Even better: I can upload and download files through it! I can send screenshots to myself and my friends! I can visit modern websites with support files for my machine, like Archive.org!
