Android Client fails when syncing

[rmsthebest]

So setup is:
Vaultwarden in a quadlet, configured with a vaultwarden.env and created keys
Caddy is the reverse proxy, only allowing local connections
Clients can only access vaultwarden when connected to a wireguard vpn

Website/web extension/ios client all work

On android I can login within the client but can't sync.
I've tried both my normal account and a fresh account without any data in it.

When I press sync this is what is logged:
maj 08 18:50:52 gibson systemd-vaultwarden[1575]: [2025-05-08 16:50:52.932][request][INFO] GET /api/sync
maj 08 18:50:52 gibson systemd-vaultwarden[1575]: [2025-05-08 16:50:52.939][response][INFO] (sync) GET /api/sync?<data..> => 200 OK

(Looks the exact same when I sync from ios)

I'm not a phone person so I'm at a bit of a loss when it comes to debugging this. Any help is appreciated.
