I encountered the following error when adding a node in the private chain today:
Fatal: Error starting protocol stack: listen tcp :30303: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.
Seeing that the port is occupied, I thought about trying to change the port, but another problem occurred:
Fatal: Error starting protocol stack: Access is denied.
Later, I found a solution: just one more parameter after the command
--ipcdisable
For specific solutions, refer to the following article:
