Hello,
I’m trying to setup the LSIO Healthchecks docker image behind a LSIO Letsencrypt reverse proxy.
Before, I successfully configured the LSIO Nextcloud image following the provided instructions and using the preconfigured nextcould.subdomain.conf
file provided with the Letsencrypt image.
As a result, I assume that my port forwarding, DNS and general Letsencrypt configuration is correct.
Unfortunately, the Letsencrypt image does not provide a preconfigured Healthchecks NGINX configuration.
For this reason, I tried to create my own configuration file by using the information I found in this LSIO blog entry.
My configuration is as follows:
Excerpt from docker-compose.yml
:
--
version: "2"
services:
letsencrypt:
image: linuxserver/letsencrypt
container_name: letsencrypt
cap_add:
- NET_ADMIN

healthchecks:
image: linuxserver/healthchecks
container_name: healthchecks
environment:

external: true
healthchecks.subdomain.conf
:
server {
listen 443 ssl;
root /config/www;
index index.php index.html index.htm;
server_name healthchecks.*;
include /config/nginx/ssl.conf;
client_max_body_size 0;
location / {
include /config/nginx/proxy.conf;
resolver 127.0.0.11 valid=30s;
set $upstream_healthchecks healthchecks;
proxy_pass https://$upstream_healthchecks:8000;
# proxy_pass https://192.168.0.203:8000;
# proxy_pass healthchecks;
}
}
When I try to access https://healthchecks.subdomain.duckdns.org
I get a 502 Bad Gateway
error.
http://healthchecks.subdomain.duckdns.org
redirects correctly to the https site and displays the same error.
Accessing the service via local network with its local IP adress and port specified results in a Bad Request (400)
.
I’m quite new to the topic and at this point I don’t know how to debug further. Any help and hints are appreciated
