Any firewall or anti-virus software installed? What error does the client give? What does netstat -nq | findstr 11434 show?

This looks like a firewall issue. ollama is listening on the right port, but the connection timed out after 21 seconds. This has the hallmarks of a firewall rule dropping TCP SYN packets.

Thanks you rick-github
curl 192.168.1.194:11434
Ollama is running

Thank you because at the time it worked but after an update from ollama it was broken so I didn't think about the firewall.
