Hi Isacord,
It sounds like you're having trouble accessing a website on your iPad, and I want to help.
If a website isn't behaving as expected, you can try clearing data for Safari to see if that gets the website behaving correctly.
Go to Settings > Safari > Clear History and Website Data.
After that, try visiting the website in Safari and seeing if the website behaves as expected.
If that doesn't work, I recommend contacting the website's administrator for guidance on what the error means and how you could resolve it.
Thank you for using the Apple Support Communities.
