What is the issue?

I'm encountering an issue with the official Ollama GUI on Windows 10 where the dropdown menu for models shows "No model found," even though I have three models installed and they are listed correctly when I run ollama list from the command line.

The server is running correctly and responds to http://localhost:11434.

I performed a clean reinstallation, including manually deleting the .ollama folders from my user directory, but the problem persists.

My computer is behind a corporate firewall, which may be related to some of the PROTOCOL_ERROR messages visible in the log, but this does not explain the core panic error when the GUI attempts to load the models.

I believe this is a bug in the GUI itself, as confirmed by the log, which shows a critical runtime error.

Expected Behavior
The dropdown menu should display the list of installed models.

Current Behavior
The dropdown menu is empty, and the message "No model found" is displayed. The log file shows a panic error when the GUI attempts to load the models.

The only way to use the GUI is to set the Airplane mode

@grester commented on GitHub (Aug 29, 2025):

I also have this problem in Win Server 2019. I'll try get my logs as well.
Side note: Possible chain of related incidents if lack of permissions to read some kind of data is the culprit #12050 #12112
