[exhilaration]

Here's what worked for me:

Run the bitwardenrs container without SSL:

sudo docker pull bitwardenrs/server:raspberry

sudo docker run -d --name bitwarden --restart always -e ADMIN_TOKEN=your_admin_token -v /bw-data/:/data/ -p 80:80 bitwardenrs/server:raspberry

Proxy through Caddy (note that I'm using DuckDNS for DNS):

curl https://getcaddy.com | bash -s personal tls.dns.duckdns

nohup caddy -http-port 999 -conf /etc/caddy/Caddyfile -envfile /etc/caddy/CaddyEnvFile -agree -email [e-mail] &

(the port 999 is because we've already got docker container running on port 80)
