This is very odd, but after updating to the latest v0.0.16, this error started showing when I use ollama. For example,if I try to run a simple "ollama list" this shows up:

Error: Head "http://localhost:11434/": dial tcp: lookup localhost: no such host

I've cleaned any DNS traces, hosts file is untouched and there are no firewall conflicts.

What could be causing this issue? Is it only happening on my end?

Hi @DreamDevourer sorry you hit this error, and thanks for creating an issue. We'll work on fixing this in the next update. In the meantime if possible make sure your /etc/hosts file has an entry like:

127.0.0.1       localhost
