Serve files from your own server :)

Basically a VPS like from https://cloud.linode.com/ and then install (and configure) https://www.nginx.com/.

It will then look like this: https://files.ekzyis.com/public/

If you want to keep things private, you can use https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication#basic_authentication_scheme (but only with HTTPS!)

It will then look like this: https://files.ekzyis.com/
