Aria2 blank/white page in webui

Hey I installed Aria2 using dietpi-software on a Raspberry Pi 4 1GB. Everything latest and updated already I believe.

My issue is I can’t access webui, or rather the page seems to load but it’s completely blank and showing white page. How can I troubleshoot this? It’s for sure port 6800, here are my rpc settings below from aria2.conf file (unsure if relevant but shows the port)

# RPC
enable-rpc=true
rpc-listen-all=true
rpc-listen-port=6800
rpc-secret=password
rpc-allow-origin-all=true
pause=false

I guess trying to connect on port 6800 is not correct. Pls have a look to our online docs on how to connect https://dietpi.com/docs/software/bittorrent/#aria2
