WebUI[edit | edit source]

There is a web UI project for Aria2C using the built in RPC server at https://github.com/mayswind/AriaNg.

A packaged version inside Docker can be found on my repository at

It looks like settings that are saved on ariang will be lost when the container restarts. When re-connecting, you may need to adjust the settings so that:

  • The RPC server is set to ariarpc.home.steamr.com.
  • Traefik is proxying port 6800 as 443
  • RPC Secret needs to be set. The container defaults to 'ariang'.
