What is the issue?

Error: listen tcp 0.0.0.0:11434: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.

I've already checked the port usage, but the error still occurs. I don't know the reason. Could someone please give me some guidance?

Something is already listening on port 11434, probably an ollama server. If you are manually running ollama serve to start a server, there's no need - the server is running. If you really want to manually start a server, you need to shut down the one that's running.

Try ollama --version to check if there is a server running.

As @rick-github mentioned this just means you have another server running on that port. Just make certain you stop the other service and then you can run ollama serve again.

I'll go ahead and close the issue as answered.
