cURL returns 200, browser timeout. AKS, LB, nginx

I try to set up simple nginx deployment on AKS. The problem is I can't open the site on browser because of timeout. Curl works perfectly. I can't figure how browser connection may vary from cURL. Into browser address bar and cURL I put nginx-service external IP:

➜  kgs -n nginx
