Moving this issue to onlyoffice.github.io repo, since the issue is not related to Docker-DocumentServer.

Hello @YangZJ781,

Thanks for the detailed report and the video — the Ollama log in it is very useful.

For context: "Invalid URL" is shown whenever the plugin fails to retrieve the model list from the given address. It is not a format check, so a 404, a connection failure and a CORS-blocked response all produce the same message. Since your log shows the model-list request actually reaching Ollama, the address itself is fine and something after that is failing.

Could you try the following?

1. Use the /v1 suffix and the hostname rather than the numeric IP:

   http://localhost:11434/v1

2. Restart Ollama with CORS opened for the desktop app:

$env:OLLAMA_ORIGINS="*"
ollama serve

3. A separate issue with your setup: copying model files directly into %USERPROFILE%\.ollama\models\blobs does not register a model — Ollama also needs the matching manifest under ...\models\manifests\. Could you post the output of ollama list? If the model is not listed there, the model list in the plugin will stay empty even once the connection works. Please use ollama pull instead of placing blobs manually.

If it still fails after that, please attach:

• the full Ollama log line for the request, including path and status code (e.g. GET "/v1/models" 200)
• the output of curl -i http://localhost:11434/v1/models
