error: Could not connect to the server 127.0.0.1:8331 (error code 1 - "EOF reached") on openbsd

[ghost]

1. running cargo run --release -- --conf btc_rpc_proxy.toml with:

bitcoind_user = "nathanael"
bitcoind_password = "[redacted]"
bind_address = "127.0.0.1"

[user.test]
password = "test"
allowed_calls = [
        "getmininginfo"
]

2. running bitcoin-cli -rpcuser=test -rpcpassword=test -rpcport=8331 getmininginfo:

error: Could not connect to the server 127.0.0.1:8331 (error code 1 - "EOF reached")

Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

the proxy is running cause netstat -na -f inet | grep 8331 gives me:

tcp          0      0  127.0.0.1.8331         *.*                    LISTEN

of course when i run bitcoin-cli -rpcuser=nathanael -rpcpassword=[redacted] getmininginfo it works (using the values inserted in the config file of btc-rpcy-proxy seen above)

has anyone an idea what i am doing wrong? something to do with openbsd?

Hi, sorry for not replying to your e-mail, last couple of days were terrible.

One more thing that comes to my mind is try to use cookie authentication. Maybe we've screwed up password authentication and I'm not sure if anyone actually tested it, since cookie files are better. Although the code looks correct from what I can tell.

[ghost]

no problem at all, thought so, maybe someone else can help or has already had the same problem

i tried in the config cookie_file = "/path/to/cookie/file" instead of bitcoind_user and bitcoind_password. then i tried bitcoin-cli -rpcport=8331 getmininginfo and of course it said error: Authorization failed: Incorrect rpcuser or rpcpassword then bitcoin-cli -rpcuser=test -rpcpassword=test -rpcport=8331 resultet in the same error as mentioned above

is that what you meant with using the cookie authentication?

[Kixunil]

Did you set /path/to/cookie/file to the actual cookie file used by bitcoind?

[ghost]

Did you set /path/to/cookie/file to the actual cookie file used by bitcoind?

yes

[Kixunil]

Could you run Wireshark or a similar tool to catch streams of those apps communicating? Ideally catch both bitcoin-cli -> btc-rpc-proxy and btc-rpc-proxy -> bitcoind; possibly also bitcoin-cli -> bitcoind

Don't forget to censor authentication if you post it, but also compare if latter two match.

i never used wireshark - this is what i get using tshark (the command line tool of wireshark):

no clue where i should have censored here something, but i just used throwaway username and password for the requests and apperently the latter two don't match

That looks like some kind of high-level overview of packets. Wireshark has "follow TCP stream" feature which is needed - it shows directly data (bytes) transferred.
