Error scraping target

[attilhacks]

Hi, i can't manage to connect to the exporter

# vi exporter.yaml 
root@btc-mct:~/bitcoin-exporter# ./bitcoin-exporter   -c exporter.yaml -v 
[2025-02-25T11:38:14Z INFO  bitcoin_exporter] bitcoin-exporter v0.5.4
[2025-02-25T11:40:34Z INFO  bitcoin_exporter] listening on http://127.0.0.1:9898

the port is open

tcp LISTEN 0 128 127.0.0.1:9898 0.0.0.0:* users:(("bitcoin-exporte",pid=288692,fd=6))

Error scraping target: server returned HTTP status 404 Not Found

any idea?
thanks
