Ok i seem to have gotten it working. In the nginx config on the jitsi server, I commented everything from this line:

location^~ /.well-known/acme-challenge/ {

to this line:

ssl_certificate_key /etc/jitsi/meet/sub.domain.com.key;

which effectively removes the server block listening on port 4444, then moves all of the location blocks and config from the listen 4444 server block to the listen 80 server block.

Awesome, thanks!

@JaredBusch When i install jitsi-meet via sudo apt-get -y install jitsi-meet, it automatically installs and configures nginx

@JaredBusch Did you change the nginx conf on the jitsi server? I followed your instructions on "Install Jitsi-Meet on Debian 9 minimal" including the nginx conf, but i'm getting a err_too_many_redirects error.
