Additional context I’m using nginx on Docker with below settings as proxy server to add Authorization header.

server {
    listen 8888;
    server_name localhost;
    location / {
        proxy_pass "https://real-verdaccio-registry/";
        proxy_set_header Authorization "Bearer ${AUTH_TOKEN}";
    }
}

I solved this issue by adding the Host header. X-Forwarded-Proto could not pass it due to GKE constraints, so I built proxy nginx using https protocol with a self-signed certificate to avoid this issue.
