Adding second server and location - help!

Ive got a working config for my DO droplet to handle the Ubiquiti Unifi Controller installed on the droplet...i figured this config out and ive had this working for ages with no issues

Basically it bumps the subdomain url from http to https and uses the port 8443 where Tomcat is running, and uses letsencrypt

But now i need to run another web server for a basic page on the same server

Ive installed lighttpd and set the port to 88, the html files are under /var/www/html/admin (/var/www/html being the correct root folder for lighttpd)

But no matter what i do adding another service or location tot he existing config leads to nothing being displayed and the usual 404 500 or 502 errors

I could use a fresh pair of eyes, ive been going around in circles for hours :)

Ive read plenty of articles, but none the wiser, im sure its something simple im missing...

Thanks in advance for any suggestions

Current config below:
