What is the issue?

Logged on to my machine today to find ollama has stopped working.

There's been no changes I can think of between when it was working 12 hours ago and now.

I've tried uninstalling and reinstalling llama but this didn't help.

>ollama --version
Warning: could not connect to a running Ollama instance
Warning: client version is 0.2.7

>ollama list
Error: could not connect to ollama app, is it running?

App logs:

GPU

Nvidia

CPU

AMD

Ollama version

0.2.7

Do you have the server log (C:\Users\Nason\AppData\Local\Ollama\server.log)?

I have the same problem, maybe this is a dumb question but has this something to do with the crowdstrike worldwide bug situation? Does ollama need to conect to a server in order to start the service locally?

@TorresIgnacio No, it doesn't need to connect to a server. But if your windows stack is messed up, who knows what else breaks.

Sounds like a firewall or anti-virus problem. You may need to change settings on whatever is blocking the port.

Thanks for the heads up, teamviewer highjacked the port. No idea why as I've had both team viewer and ollama on this PC for months without issue.
