Could not connect to Bitcoin RPC server outside local host using bitcoind-0.18.0

Question

I upgrade bitcoin core from 0.16.3 to 0.18.0, But I can not connect to RPC server outside local host.

I use the following parameters as bitcoin.conf:

testnet=1
server=1
daemon=1
rpcallowip=0.0.0.0/0
rpcuser=xxxxxx
rpcpassword=xxxxxxx
[test]
rpcport=8383 
wallet=test_btc_wallet.dat

Answer 1

You need to explicitly bind it to 0.0.0.0 by using rpcbind=0.0.0.0
