couldn't connect to server: EOF reached (code 1)

couldn't connect to server: EOF reached (code 1) I'm running a full node on my raspberry pi3. I try to do a simple command such as bitcoin-cli getblockchaininfo but I always get this error: error: couldn't connect to server: EOF reached (code 1) (make sure server is running and you are connecting to the correct RPC port) My bitcoin.conf file looks like this: Bitcoind options server=1 daemon=1 reindex-chainstate=1 reindex=1 txindex=1 disablewallet=1 listenonion=0 Connection settings rpcuser= * rpcpassword=* rpcport=8332 rpcallowip=127.0.0.1 rpcthreads=10 I also tried to get a command with "bitcoin-cli -rpcuser: * - rpcpassword=* -rpcportt8332 getblockchaininfo". But this also didn't work. Does someone has some advice or experience with this error? https://ift.tt/2D82TLW

How to import p2wsh-in-p2sh multisig as watch-only?

How to import p2wsh-in-p2sh multisig as watch-only? I've created a p2wsh-in-p2sh multisig address using an offline node. I have the address and redeem script, as provided by bitcoin-cli addmultisigaddress on the offline node. How do I import this as a watch-only address on an online node, so I can use the online node to create transactions ? I have tried the following: $ bitcoin-cli -testnet -rpcwallet=glacier importmulti '[{ "scriptPubKey": { "address": "2MzqiaZzpLT2SSBfsFqqo3FpZsP8g6WTvyC" }, "timestamp":"now", "redeemscript":"5221029f531503facdac2496f50a446d9bd29846a06a04a45e3845b656bb471df422fc2102e30787703a990e4015a2cb9071fcfd1c7d4641fb294e4b4c3f5f6b450a1925132102da28088a8022651171c4f13429b98709dabe13bc6da526537fdd2d0730dd2dbb2103286c96ecaa850a6ba43cc45fbb539c1fb1d65c23cc0f3cd09fcf9765826ff9de54ae", "watchonly":true, "label":"Glacier 2012-12-21" }]' [ { "su...
