Topic: Bitcoin-CLI - Cannot connect to the server (Read 129 times)

There is a chance you've screwed it up with reproduction, and have a logical error (which wouldn't appear after compiling). But, I doubt that's the case.

Does it print it if you delete bitcoin.conf?

It's normal there is no genesis black since I'm trying to locally generate a blockchain based Bitcoin Core. For this purpose, I have changed the port, reproduce a Genesis block hash, etc. and succesfully rebuilt and compile without error.

The above error message started after I've created the bitcoin.conf file.

I supposed Bitcoin Core automatically generate a local genesis block if is this last does not exist.

There's your problem.

And what logs says?


On the other hand - is .cookie file created? Did you try to connect to server using that file instead of hardcoded password?

Then this should be solved first before the original question since this must be the vey reason why bitcoin-cli can't query bitcoind.

For that, provide the whole logs as instructed above.
