   When I’m trying to use bitcoin-cli while bitcoind running it displays error message :

    0Make sure the bitcoind server is running and that you are connecting to the correct RPC port.```

   Hello,

   Now it’s solved but initially it was only : launch bitcoind In another window launching bitcoin-cli getblockchaininfo command.

   What weird was the absence of message : bitcoin-cli command not found.

   Because now I think it’s because I didn’t call the path where is bin/bitcoin-cli.

   Or maybe because the chain didn’t finished to load and so I should wait.

   I don’t know exactly but now it’s solve I will close it.

   Thank you very much for your answer !!🙌

   Adding more context to this closed issue in case other people stumble on it too.

   I was able to reproduce this error with a script running Bitcoin Core 25.0 and 24.0.1 (x86_64-linux-gnu on Ubuntu).

   Steps to reproduce:

   1. Delete the data directory.
   2. Launch bitcoin-qt --server.
   3. Immediately check the chain state with bitcoin-qt getblockchaininfo.

   The RPC server doesn’t have enough time to initialize, so the call to port 8333 fails.

   Fixed the issue by using the rpcwait option: bitcoin-cli --rpcwait getblockchaininfo
