auroraoss.com blocks Tor connections (except through Tor Browser), breaking the token dispenser

The https://auroraoss.com server almost always times out requests made over the Tor network but not through the official Tor Browser (which is apparently whitelisted somehow). This breaks the Aurora Store token dispenser for anonymous logins: "Requesting new session" -> "Read timed out". It also breaks access to https://files.auroraoss.com through e.g. Vanadium torified via Orbot, etc.

Maybe it's due to an OVH anti-DDOS setting?
