Issue with ariang once behind a proxy

[masterlog80]

Hello,
I have run aria2-pro and ariang on my Docker with a Compose file and everything is running fine. I have put ariang behind my Proxy (traefik) in order to have a secure connection my own SSL Certificate but that caused an issue as it can't connect anymore to aria2 as it seems required HTTPS:

I am assuming this happens because the browser is using HTTPS. Is there a way to force ariang keep using HTTP?

Regards
