'pixlet login' on headless server

Does anyone know if we can pixlet login on a headless server? I’m SSH’d into a server that I’d like to use to push a local *.webp image, but I need to login to pixlet first. login.tidbyt.com wants to redirect to localhost, but that’s not the server that generates the link. When I curl the localhost:8085… link, pixlet throws a getting auth token: state mismatch in 3-legged-OAuth flow error.

Any ideas? Thanks!
