Connection Refused

Question

I am running bitcoind in unbuntu 16.04. And a web server running in docker container. When I excuted curl in container bash curl --user user:pass --data-binary '{"jsonrpc":"1.0","method":"getblockchaininfo","params":[]}' -H 'content-type:text/plain;' http://127.0.0.1:18332/ response is curl: (7) Failed to connect to 127.0.0.1 port 18332: Connection refused

docker inner address 172.17.0.1 . However, curl in command line directly is ok.

Below is .conf setting: server=1 testnet=1 rpcuser=user rpcpassword=pass rpcallowip=172.17.0.1 rpcport=18332 rpcconnect=127.0.0.1

I have tried all possible combinations of ip address and port number. All the results are 'Connection refused' Can anyone advise me how to resolve the problem? Thanks
Regards, Max

Answer 1

Since Bitcoin Core 0.17 certain config file options are net-specific. In particular this is true for rpcport.

This means you need to write it as test.rpcport=18332 now.

More information can be found in the 0.17 release notes: https://bitcoincore.org/en/releases/0.17.0/ (look for "Configuration sections for testnet and regtest").

Answer 2

in the versions 0.15+ bitcoind rpc require rpcauth in the bitcoin.conf file.

rpcauth = user: password //generated with python script
