Website is not displaying ๐Ÿ˜Ÿ

Hello,
I made a test website completely with Hype.
The problem is that my test website is not displaying in Chrome, Firefox and sometimes in Opera. In Safari works everything fine.

Is this problem with browser or with website?
And how can I fix this issue?

Regards,
Matus

Seems to work ok here on Safari,firefox and chrome.

Ditto here + Opera.

@MarkHunte @JimScott It seems like problem with cache.

Okay on Mac Safari * IOS devices here.

This may help:

Thanks @Daniel I tried adding .htaccess file, but I got this error: https://grafik.gq/test
Any ideas how to fix it?
