I successfully installed a self-hosted Bitwarden using docker on Ubuntu 16.04 VPS two days ago. Now I’m going insane. Every time I try, using a new domain and VPS, to run the installation, after I select the domain and confirm the Let’s Encrypt certificates request, certbot halts everything with the following error.
"Requested domain ./bitwarden.sh is not a FQDN because it contains an empty label.
Tried different users, domains, VPS, nothing. Can’t install it again… Also googling it doesn’t seem to get me to any useful results.
