Use IIS with URL Rewrite as a reverse proxy - ERR_TOO_MANY_REDIRECTS

Grafana Configuration
1

Hello people,
I’ve been trying to configure the Grafana on IIS using reverse proxy but without success.
I followed the steps in the documentation ( Use IIS with URL Rewrite as a reverse proxy | Grafana Labs) and watch a tutorial (Grafana and IIS - Windows Server Installation Setup and Configuration - YouTube), but, I always have the error ERR_TOO_MANY_REDIRECTS in the browser.

Grafana version: 10.0.1.

My custom.ini config:

[server]
# Protocol (http, https, h2, socket)
protocol = http

# The ip address to bind to, empty will bind to all interfaces
;http_addr =

# The http port  to use
http_port = 8080

# The public facing domain name used to access grafana from a browser
domain = localhost

# Redirect to correct domain if host header does not match domain
# Prevents DNS rebinding attacks
;enforce_domain = false

# The full public facing url you use in browser, used for redirects and emails
# If you use reverse proxy and sub path specify full url (with sub path)
root_url = %(protocol)s://%(domain)s:%(http_port)s/grafana/

# Serve Grafana from subpath specified in `root_url` setting. By default it is set to `false` for compatibility reasons.
serve_from_sub_path = true

My web.config:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="Grafana Inbound Rule" enabled="true" stopProcessing="true">
                    <match url="grafana(/)?(.*)" />
                    <action type="Rewrite" url="http://localhost:8080{R:2}" logRewrittenUrl="false" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

I don’t know what happens so I need help.
Thanks

Welcome @byander

Why do you want to run grafana via IIS ?

Hello @yosiasz ,
It’s because currently, the company where I work uses only Windows Servers. Unfortunately, for now, I can’t use Linux Server.

I found on Github this issue (Azure AD redirect not working behind IIS reverse proxy · Issue #32034 · grafana/grafana · GitHub) and I put in the “Server proxy settings” and then configure ARR the option “Reverse Proxy” with the value “localhost:3000”.

The default value is empty and the documentation doesn’t mention this field to set.

When I set it to localhost:3000, it works but I don’t know if is the best way to solve it.

why not install it as a windows service?

install as service
start
done

sc.exe create _grafana-10.0.0 binpath= C:\LGTM\grafana-10.0.0\bin\grafana-server.exe

@yosiasz ,
I installed it as a service.
But I would like to use the proxy reverse from IIS to Grafana service and this way hide the port from URL.
