It sounds like the configuration changes that were made to your Bitcoin Core are incorrect. Try checking them for mistakes against the instructions you were following, or remove them to use the default configuration. If you want concrete help with the error, please share details on the configuration you are using (please obscure sensitive information like access credentials if any appears in the configuration).
