Can’t start bitcoind if rpcuser and rpcpassword are specified #14261

   I am running Bitcoin Core v016.2 on Ubuntu Server 16.04.03 and I have interesting problem. I can start and run bitcoind only if no rpcuser and rpcpassword is specified inside bitcoin.conf. If bitcoin.conf contains this two parameters set, it will start for a while and ends with that:

   That’s it. No daemon is running. Without rpcuser and rpcpassword there, it’s running fine, but communication with daemon is not posible due to authentication. Any idea ?

   bitcoin.conf content: listen=1 server=1 daemon=1 txindex=1 testnet=0 rpcuser=admin rpcpassword=verylongrandompassword

   I get a similar problem, except for me, it is having txindex=1. If I remove this line from the config file, or set txindex=0, bitcoind will start up fine. Otherwise, bitcoind shuts down right away.

   Running Ubuntu 16.04 LTS bitcoind version 160300

   @teknari Note that you can’t change txindex between restarts without a reindex. bitcoind should print an appropriate error in that case.

   @hiddenvs Note that you have to provide the datadir and chain to bitcoin-cli, so that the appropriate authentication values can be read from the cookie file

   @MarcoFalke That worked for me. Thank you very much!
