500 Internal Server Error Conecting to websites

A friend of mine can’t access any cloudfare websites (including cloudfare’s website itself) due to this issue as provided in the image. Any tips for how to fix? She’s restarted the device and the wifi with no result. Using a VPN fixes the issue oddly enough
