I'm having trouble getting my web frontend working. When I try to access http://localhost/mailman3 I get a 503 error and the following in the apache2 error.log:

Is mailman-web running? If so, what is the content of /etc/mailman3/uwsgi.ini if you are using uwsgi or /etc/mailman3/gunicorn.conf if you are using gunicorn?
What do you get from http://127.0.0.1:8000/mailman3?
This is the relevant part of apache2's 000-default.conf:
<IfModule mod_proxy.c> ProxyPreserveHost On ProxyPass "/mailman3" "http://127.0.0.1:8000/mailman3" ProxyPass "/archives" "http://127.0.0.1:8000/archives" ProxyPass "/accounts" "http://127.0.0.1:8000/accounts" ProxyPass "/admin" "http://127.0.0.1:8000/admin" ProxyPass "/user-profile" "http://127.0.0.1:8000/user-profile" </IfModule>
What is a bit confusing but probably unrelated is this is in the virtual section for port 80 rather than port 443. I don't see any errors anywhere else.
It needs to be there to support http://localhost/mailman3, but for https://localhost/mailman3, it needs to be in the port 443 section.
