How to install and configure Tdarr?

I tried configuring Tdarr App on my TrueNAS server but i continue getting errors: i configured config, storage, transcode ecc on host path, configured with full control for all users, yet i get “auth error” on every path, even when trying to download profiles from the community.
I managed to create my own profile but no transcoding start, i tried installing also Tdarr Node but yet same authorization error… has anyone managed to successfully install it or has some guide?
