Just tried and get Sonarr (sonarr.tv) to work thanks to ynh_redirect (sonarr is manually installed through the repo as described here
url : dedicated_subdomain.domain.tld
path : /
redirect_from (i forgot the real variable name) : http://127.0.0.1:8989
type: proxy
and it works \o/
As each and everytime, thanks to the amazing work. I couldn’t have easily configured a reverse proxy (the name and concept of which i discovered reading the readme and the forum) so easily and quickly
Ynh rocks
