Bitwarden Docker Blocks Port 80

I followed the instructions to install bitwarden onto my VPS

curl -Lso \
  && chmod +x
./ install
./ start

It works fine, but now port 80 is blocked. I understand the docker script uses this port for let’s encrypt. The problem is that I can’t run websites from the same VPS since port 80 is blocked. In addition, I can’t get wildcards SSL from certbot because it conflicts with Bitwarden’s certificate.

I want to be able to install bitwarden as a subdomain on my VPS with other subdomains for things like tt-rss, next cloud, wallabag etc.As well as run multiple domains from the same VPS. How do I work around the requirements of Bitwarden?
