Leo AI does not work on Ubuntu 24.04

Description of the issue:
Every time i try to launch built-in models, such as mixtral or llama, i get the same error: “There was a problem connecting to Leo. Check your connection and try again.”. I added my own Mistral Large api - frankly, it worked just fine.
