Why does the "bitcoin-cli getinfo" command no longer work with me ?

[chegmarco]

Hello.
   I would like to know if the Bitcoin-cli command works with or without Internet ?
I am not Internet and when I run "bitcoind - daemon" then "bitcoin-cli", I get the error below:
seclinux@seclinux-HP-15-Notebook-PC:~$ bitcoind -daemon
Bitcoin server starting
seclinux@seclinux-HP-15-Notebook-PC:~$ bitcoin-cli getinfo
error: Could not locate RPC credentials. No authentication cookie could be found, and no rpcpassword is set in the configuration file (/home/seclinux/.bitcoin/bitcoin.conf)
seclinux@seclinux-HP-15-Notebook-PC:~$

So do you think the error is due to lack of Internet ? Without Internet "bitcoin-cli" should work or not ?

IMPORTANT: I specify that I launched this morning "bitcoin-cli getinfo" just after the reinstallation of Bitcoind (with Internet in the morning of course) and it worked rather. But I do not know why it does not work anymore. Is it because of the Internet that I do not currently ?

Thank you for your explanation.

If you did not set an rpcuser and rpcpassword in the bitcoin.conf file, then that is why bitcoin-cli is not working. That has nothing to do with your internet connection. Read the error that it is telling you. Make sure that either both rpcuser and rpcpassword are set, or they are not in the bitcoin.conf file at all. With the latter case, if neither option is set, it will use an automatically generated rpc credentials which are also stored in a different temporary file in the datadir.

But of course I have set the connection parameters rpcuser and rpcpassword. But why this error

Are you sure that you have spelled the option properly? Are you sure that the bitcoin.conf file is located here: /home/seclinux/.bitcoin/bitcoin.conf?

I restarted the PC after several hours and the command "bitcoin-cli" works well now. Thank you.
