Same issue to me. Connecting from Italy (my ISP is FastWeb). And no... it's not an issue with my Internet connection. USA and Japanese servers are fine, only European servers have this issue since a very long time. Sometimes they work but many more times they have the issue described by Malachiel.

i wanna add to this issue that cloudflare warp not download avatars (all robot, after queue) now (2026), until 2025, worked correctly

I noticed from october 2025 cloudflare crash, many people that connect to European world have issue with world join leaning the error: "Behaviour] Lost connection to realtime network while waiting to enter room: Disconnected - initial join - La tua connessione a VRChat è scaduta. Verifica la tua connessione e riprova." and it took 5-8 retry to join a world

Plus sometimes i hear the player voice in these world crippling

Using Cloudflare WARP it help to fix the voice player (still not sure anyway) but don't help with world joining

There are no issue with other realm, like american or japanese

I am italian and i am using Fastweb ISP
