Nginx Reverse Proxy - Infinite Redirect

You should see two buttons. “Copy” and “Open” . Until you don’t, it means that KPI cannot talk with Enketo Express. It must be related to your double proxy configuration.

I cannot test it soon but if I do, I let you know.

Actually - this is without the double proxy. I’ve put Kobo behind a ELB just to eliminate that as a possibility for now. Sorry - I should have mentioned that.

Did you run the setup after again ?

Yep I ran the I did not remove the old instances/app directories though

Ok, I’ve made a test on my own and every works as expected.
I’ve created a proxy with NGINX hosted on the same EC2 instance.

Browser -> 443 - > ELB -> 80 -> NGINX Proxy -> 8080 -> Kobo NGINX.

The NGINX proxy is latest version (1.19) of NGINX in docker container.
I changed nothing except the default.conf
This is the NGINX Proxy configuration

server {
    listen 80;
    server_name $hostname;
    server_tokens off;

    # Allow 100M upload like KoBo NGINX
    client_max_body_size 100M;

    location / {
        proxy_pass;  # is the docker interface (`ifconfig docker0`)
        proxy_set_header    Host                $http_host;
        proxy_set_header    X-Real-IP           $remote_addr;
        proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Proto   https;

I used KoboInstall Version: 2.4.2 (build 2.020.24b)

I can create projects, deploy to KC, submit data through Enketo. (Open button works)
Hope it helps.
