Error processing request URL GET /Items//playbacki

In the Jellyfin Nginx doc there is this setting you don't have.  Maybe this is it?

Code:

    ## The default `client_max_body_size` is 1M, this might not be enough for some posters, etc.
    client_max_body_size 20M;

You also don't have this block.  Not sure how important it is.

Code:

    location = / {
        return 302 http://$host/web/;
        #return 302 https://$host/web/;
    }
