Original GitHub issue: https://github.com/ollama/ollama/issues/8719

What is the issue?

Hi, I was using Ollama in powershell, and whatever command I type, it gives me "config.go:45: WARN invalid port." I have tried to change the Ollama_Host environment variable, but it does not change anything. Ollama still works, but it is way slower. Can you please tell me how to fix it? I expected a direct response instead of "config.go:45: WARN invalid port, using default port=127.0.0.1 default=11434"

OS

Windows

GPU

Intel

CPU

Intel

Ollama version

0.5.7

What's the output of

echo %OLLAMA_HOST%

or

echo $env:OLLAMA_HOST

The reason inference is slow is your drivers are old:

time=2025-01-30T10:19:39.464-06:00 level=INFO source=gpu.go:630 msg="Unable to load cudart library C:\\WINDOWS\\system32\\nvcuda.dll: symbol lookup for cuCtxCreate_v3 failed: The specified procedure could not be found.\r\n"

Update your Nvidia drivers.

Also, I have intel drivers?

Sorry, must have been looking at someone elses log files. You have no detected GPUs.

since I can't use the export command on windows 11, I changed the system environment variable to OLLAMA_HOST and the value to 127.0.0.1

it still does the same thing

After restarting ollama and the terminal, it still says the same thing. Maybe it is because I forgot to restart Ollama and terminal right after I set the variable.

Somewhere, somehow, you have a mis-configured OLLAMA_HOST. What happens if you remove OLLAMA_HOST from the environment configuration, restart ollama, close the command terminal window, open a new command terminal window, run echo %OLLAMA_HOST%, then run ollama -v.

That image is command prompt, but when I run echo Ollama host in Powershell 7, it just gives me %ollamahost%

In PowerShell, you need to run echo $env:OLLAMA_HOST.

So we see that OLLAMA_HOST is malformed. You need to fix that.

Make sure to confirm and exit any subwindows of Edit the system environment variables before opening a new terminal to ensure changes take affect.
