Hello,
I have a nginx proxy which does a proxy_pass to a istio service.
server {
listen 3900;
client_max_body_size 0;
index index.html;
server_name localhost;
root /var/www/public;
location /api-url {
rewrite ^/api-url/(.*)$ /$1 break;
proxy_pass https://myapp.com;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $proxy_host;
proxy_cache_bypass $http_upgrade;
}
}
In Istio I have a virtual service for myapp.com.
I get a 404 through the proxy_pass but a 200 via curl.
curl to nginx “http://localhost:3900/api-url/api/v1/completions?prefix=&field=sessionTags”
Returns a 404
Istio ingressgateway access log for this call:

I can’t figure out what the issue is with the nginx proxy_pass module.
