I suddenly can't open hyperspacevault.com on any of the three computers in my home, including one that has never visited the site before. My phone can still access it while connected to the same Wi-Fi. I've restarted the modem, router, and computers, reset the network settings, and tried several ipconfig commands from online troubleshooting guides, but nothing has helped. I'm not very familiar with networking, so I'd appreciate help understanding what might be causing this and what the error means.

There may also be a routing problem between your internet provider and the server hosting the site. Since the phone works on the same Wi-Fi, compare whether it is truly using Wi-Fi rather than mobile data. If it is using Wi-Fi, the issue may be specific to how your provider resolves or routes the site. These problems sometimes clear up after the hosting provider or ISP corrects its configuration.
The fact that multiple computers fail while the phone works points away from a single computer setting. Check whether the phone is opening the site over HTTPS and compare the exact address and error message. A DNS or certificate issue could affect the computers differently depending on their browser, DNS settings, or cached records.
What exactly happens when you try to load the site? The browser’s error message would be especially useful. It’s also worth testing another browser and clearing the browser cache, although that probably wouldn’t explain the failure on multiple computers.
The site appears to have had a certificate problem, with the browser reporting a certificate name mismatch. That can happen if the server is misconfigured, the certificate recently expired, or different servers are presenting different certificates. I wouldn’t bypass the warning or enter sensitive information until the site owner fixes it.
