Most likely you are running chat-ui over HTTP. The recommended option is to setup something like NGINX to handle HTTPS and proxy the requests to chat-ui. If you really need to run over HTTP you can add ALLOW_INSECURE_COOKIES=true to your .env.local.
Make sure to set your PUBLIC_ORIGIN in your .env.local to the correct URL as well.
