BitcoinD RPC Server

[XavierNauze]

Hi there,

I have a small problem with my server bitcoind, when i taping example : bitcoin-cli getbalance i have that error :

error: couldn't connect to server: unknown (code -1)
(make sure server is running and you are connecting to the correct RPC port)

But the port its open, how i can resolve that ?

System : Ubuntu Server

Bitcoin.conf :
prune=550
rpcport=8332
maxconnections=125
maxuploadtarget=0
rpcuser=USERHIDDEN
rpcpassword=PASSWORDHIDDEN
daemon=1
keypool=100

A couple of things...

Use your RPC connect username and password in the command.

Code:

bitcoin-cli -rpcuser=userhidden -rpcpassword=passwordhidden -rpcport=8332

Check your firewall rules:

Code:

sudo iptables -L

or

Code:

sudo ufw status

For debugging, you can try turning off your firewall

Code:

sudo ufw disable

, dont forget to turn it back on.

If it was blocked locally, you can add a rule:

Code:

sudo ufw allow from (source ip) to (RPC IP) port 8332 proto tcp

example: sudo ufw allow from 192.168.1.1 to 192.168.1.1 port 8332 proto tcp

Good luck

I got similar problems this where caused by closed ports...

I don't know about the current defaults, but a

Code:

server=1

may also help

Thanks! For anyone else reading, I noticed that bitcoin-cli worked properly when bitcoind was invoked via the command line, but not when running the GUI.

Adding "server=1" to bitcoin.conf fixed this issue.

bitcoind will default to server=1. bitcoin-qt will not. So if you want to use the RPC server while running bitcoin-qt, you need to set server=1
