how to troubleshoot ERR_TOO_MANY_REDIRECTS

[genfoch01]

I deployed nginx proxy manager via docker-compose

I set up my first host (bookstack ) like so :

with an ssl cert (force ssh and http/2 support )

works perfectly.

so I have an old nas (it does not support adding a cert: its old ) so I thought i'd use nginx in front of it to get rid of the annoying ssh warnings.

I don't have ssl set up because I cant get the proxy to work.

when I try to go though the proxy server I get

the access log shows :
[22/Sep/2023:15:41:58 +0000] - 302 302 - GET https ilios.citystates.net "/admin" [Client 192.168.10.105] [Length 218] [Gzip -] [Sent-to 192.168.10.155] "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36" "-"

the fallback_error.log shows this;

2023/09/22 15:04:50 [error] 3577#3577: *22414 open() "/var/www/html/login" failed (2: No such file or directory), client: 192.168.10.105, server: localhost-nginx-proxy-manager, request: "GET /login HTTP/1.1", host: "dev2.citystates.net"

I am not sure how to attack this problem. It seems like it should be simple, i'm just not sure where to start.

thanks for your time,
GF

Is cloudflare your name server? Make sure your ssl in CF is full or strict.

thanks for the response, sorry for the late reply. I finally found the issue. I needed to add the APP_URL directive to the bookstack composer then everything started to work.
