i have a bitwarden setup running with the docker containers, working fine so far, running behind a nginx proxy.
Recently i changed the proxy setup due to a new dynDNS name and therefore received new let’s encrypt certificates. With the new certificates the Android client will not connect any more, it shows an “Exception message : Handshake failed”
I can open the bitwarden url in Chrome and Firefox with no problems, only the app is showing the error.
What i found out so far : the certificates differ in the way they where generated.
The old and working setup has a certificate signed with a RSA-4096 bit key, the new one has a Elliptic Curve key EC-384
Can someone else confirm a working setup with elliptic keys in let’s encrypt certificates ?
