You have invalid authentication details for the RPC.

@uaktags we should probably handle this new error to report what the problem is - I'll take a look into it

Guessing he is upgrading from an older version, his user/pass is probably not updated to username/password.

Guessing he is upgrading from an older version, his user/pass is probably not updated to username/password.

That was exactly my friend!
I made the update in my source and it worked!

[uaktags]

@TheHolyRoger quick and dirty would be:

const Client = require('bitcoin-core');
if(settings.wallet.password || settings.wallet.username){
}else{
  settings.wallet.password = settings.wallet.pass;
  settings.wallet.username = settings.wallet.user;
}
const client = new Client(settings.wallet);

in explorer.js it's not a error handling measure, but it's a starting point. Perhaps instead, error handling should look into the ./bin/instance to check that everything is updated for the new versions (so if any settings.json things are changed/updates needed and they're not found, we can warn/error out before launching numerous workers for the instance.) Within there, during npm start, we can test RPC functionality, check settings.json for good configurations/upgrades needed, etc and stop/continue as per.

But regardless, I think his settings.json is from 1.6.1, @digitalcoin1 please confirm and double check your
settings.wallet.password and settings.wallet.username (it use to be called settings.wallet.pass and settings.wallet.user)

[uaktags]

Perfect, thanks @digitalcoin1 for the update.

Reopening the issue and will rename it for the fact we should have error-handling for this required upgrade (it will likely cause issues for others). DigitalCoin, you can mute this issue if you'd like!

[LightBurdenOfficial]

Thanks!

When I change from user/pass to username/password I get this error
