Hello, I’m hosting a #Vaultwarden server behind #Caddy 2.10 and made the following test:

Tuning Caddy to allow only #PQC curves:

	tls {
		curves x25519mlkem768
	}

Trying to connect with #Firefox Mac -> OK
Trying to connect with #Bitwarden #android client -> Fail

Without the #TLS tuning, the Bitwarden Android client will happily connect to the server.

Is it a problem with the Bitwarden Android client or with Android, or both?

Hey @bitwarden , ideas? ️

@patpro Hey there, this is usually resolved by updating your server, but don't hesitate to reach out to their support channels.

@bitwarden in my setup, the bitwarden client creates a TLS session with the Caddy server only. Caddy acts as a proxy to reach the backend.
Caddy is up to date.

@patpro Thanks for the additional detail, to clarify, please make sure your Vaultwarden server is up to date.
