[SOLVED] OPNsense - NGINX => internal website

[MichaDebuss]

Hello,

I have installed the ghost.org system (website, running on Proxmox).

It works very well locally.
IP: 192.168.5.55

Unfortunately I can't get to the page via url. I used NGINX in the OPNsense for this purpose.

That is my configuration in OPNsense

Dynamic DNS:
(works fine) website.example.com

ACME Client:
SSL-Certificate: (works fine), ACME-Status OK website.example.com

Firewall - Rules - WAN:
Protocol: IPv4 TCP
Source: *
Port: *
Destination: WAN address
Port: 80,443  (as ALIAS)
Gateway: *
Schedule: *


I have configured the following in OPNsense - Services - Nginx:

General Settings:
Enable nginx: TRUE

Upstream Server:
Description: Website
Server: 192.168.5.55
Port: 80
Server Priority: 1
Max. Connection: 1000
Max. Failures: 10
Fail Timeout: 900

Upstream:
Description: Website_Pool
Server Entries: Website
Load Ballancing Algo: Weighted Round Robin
Enable TLS (HTTPS): FALSE
nothing more configured on this page

Location
Description: Website_location
URL Pattern: /
Upstream Servers: Website_Pool
Force HTTPS: TRUE
nothing more configured on this page

HTTP Server
HTTP Listen Address: 80
HTTPS Listen Address: 443
Default Server: FALSE
Server Name: website.example.com
Location: Website_location
TLS Certificate: website.example.com (ACME Client)
Client CA Certificate: R3 (ACME Client)
Enable Let's Encrypt Plugin Support: TRUE
HTTPS Only: TRUE
nothing more configured on this page

Unfortunately I get an error message when calling https://website.example.com
This page isn't working
website.example.com redirected you too many times.
ERR_TOO_MANY_REDIRECTS

Does anyone have any idea what could be causing this?
Somehow I can't find the error.

Thank you for any advice.

Best regards

Michael

TOO_MANY_REDIRECTS means that there is a redirection loop.

Test with curl why it happens (from the same client that couldn't connect with its browser):

Test with HTTP:

Code Select Expand

curl -L -v --max-redirs 10 http://example.com

Test with HTTPS:

Code Select Expand

curl -L -v --max-redirs 10 https://example.com

Look for the "location:" header in the output and you can see which locations cause the redirection loop to happen.

Thank you for your help.

The location is always website.example.com (see logfile attached). ???

Do you have any ideas what the problem could be?

[MichaDebuss]

I have tweaked a few things. It works now.  :)

Changed the following:
Upstream Server: Port changed to 443
Upstream: TLS Enabled = TRUE
Location: Force HTTS = FALSE

Many thanks for your support @Monviech .
That gave me the decisive food for thought.
