Failed to start monitoring HTTP server at 127.0.0.1:4224

Hi there,

I've installed bitcoin core v27.0 and this electrs server. There is no error when I install them.

But I get this error when I start electrs server.
Failed to start monitoring HTTP server at 127.0.0.1:4224

I also install Prometheus and it works fine.

This is the command to run electrs:
/path/to/electrs/target/release/electrs --blocks-dir=/path/to/bitcoind/blocks --cookie=rpcuser:rpcpass --daemon-dir=/path/to/bitcoind --network=mainnet --db-dir=/path/to/esplora_db

Settings in bitcoin.conf file
listen=1 txindex=1 server=1 daemon=1 prune=0 dbcache=7500

What should I do to solve this error?

do you have some other service on your host that is listening on port 4224? that is the port served by electr's prometheus exporter, and it may be conflicting. You can ask electrs to listen on a different port with this option:

--monitoring-addr :

No, I don't have any service that is listenning on port 4224.

try it again with a different monitoring-addr (ip:port)
