1. The problem I’m having:
I am trying to setup timeouts in my caddy configuration file (JSON format) and am not able to get my caddy file to validate.
I am using the documentation found here with little success: Caddy Timeout Documentation
2. Error messages and/or full log output:
I have a small simple caddy file called test.json to demonstrate the issue I am having:
{
"apps": {
"http": {
"servers": {
"timeouts": {
"idle":"30s",
"read_body":"10s",
"read_header": "15s",
"idle": "5m"
},
"srv0": {
"listen": [":443"],
"routes": [
{
"match": [{
"host":["example.com"]
}],
"handle": ["file_server"]
}
],
"automatic_https": {
"disable_redirects":true
}
}
}
}
}
}
The timeout section does not pass the caddy validation routine. Here is the command and error I get from the validation:
$ sudo caddy validate --config /etc/caddy/test.json
2025/04/07 17:11:12.239 INFO using provided configuration {"config_file": "/etc/caddy/test.json", "config_adapter": ""}
Error: loading http app module: decoding module config: http: json: unknown field "idle"
3. Caddy version:
Here are my versions of Caddy/OS (Caddy is the only software I have installed and running on this server):
jim@caddyrevproxy:/etc/caddy$ caddy version
2.6.2
jim@caddyrevproxy:/etc/caddy$ uname -a
Linux caddyrevproxy 6.8.0-56-generic #58-Ubuntu SMP PREEMPT_DYNAMIC Fri Feb 14 15:33:28 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux
4. How I installed and ran Caddy:
a. System environment:
Here are the commands I ran to install and get caddy running:
sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https curl
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/caddy-stable-archive-keyring.gpg] https://dl.cloudsmith.io/public/caddy/stable/deb/debian all main" | \
sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install -y caddy
sudo systemctl enable caddy # enable on boot
