You have OLLAMA_HOST set incorrectly.

$ OLLAMA_HOST='C:\Users\123\AppData\Local\Programs\Ollama\ollama app.exe'
$ ollama run llama3.1
2024/09/18 09:14:26 config.go:45: WARN invalid port, using default port="\\Users\\123\\AppData\\Local\\Programs\\Ollama\\ollama app.exe" default=11434

Error: Head "http://C:11434/": dial tcp: lookup C: no such host

You should either unset it, or set it to the IP and port where your ollama server is running

$ OLLAMA_HOST=http://127.0.0.1:11434
$ ollama -v
ollama version is 0.3.10

umm I think i followed this rules etting environment variables on Windows
On Windows, Ollama inherits your user and system environment variables.

First Quit Ollama by clicking on it in the task bar.

Start the Settings (Windows 11) or Control Panel (Windows 10) application and search for environment variables.

Click on Edit environment variables for your account.

Edit or create a new variable for your user account for , , etc.OLLAMA_HOSTOLLAMA_MODELS

Click OK/Apply to save.

Start the Ollama application from the Windows Start menu. but still cant use

OLLAMA_HOST is wrong.
ollama_host
You should either unset it, or set it to the IP and port where your ollama server is running.
