Vaultwarden not reachable after update to latest version

I have updated to the latest version of vaultwarden docker image. After the update to service was not reachable anymore. Not via web or any clients.

I used traefik 2 and the config was okay. Showing the correct ip and port in the traefik dashboard. Also my other services are still working.
Downgrading to 1.30.3 fixed the issue.

Do you have similar problems?

Vaultwarden container has this compose:

version: ‘3’

services:
vaultwarden:
image: vaultwarden/server:1.30.3 # Latest broken
container_name: vaultwarden
volumes:
- data:/data
restart: unless-stopped
networks:
- public
environment:
- SIGNUPS_ALLOWED=false
labels:
- traefik.enable=true
- traefik.http.routers.vault.rule=Host(mydomain)
- traefik.http.routers.vault.tls=true
- traefik.http.routers.vault.tls.certresolver=letsencrypt

volumes:
data:

networks:
public:
external: true

FWIW 1.30.4 and 1.30.5 work(ed) OK in my case.
I’m not using compose (just docker), and I use nginx as reverse proxy.
