HTTP Error 403: Forbidden

I have launched sglang backend on runpod, and when I open /get_model_info endpoint in browser it works, but when I try it locally it throws following error

set_default_backend(RuntimeEndpoint(os.getenv("SGLANG_URL")))

Traceback (most recent call last):

Upd: it neither works on server when I use its full url with "https", but again it works if I use "http://localhost"
