1. Caddy version (caddy version
):
v.2.2.1
2. How I run Caddy:
I am executing the Caddy.exe and php_cgi via a script simply calling caddy.exe run
a. System environment:
Windows 10
b. Command:
caddy run
d. My complete Caddyfile or JSON config:
localhost:443
root * ./
templates
file_server browse
php_fastcgi 127.0.0.1:6545 php
3. The problem I’m having:
I am trying to run a PHP backend on Caddy, when I open up localhost:443/index.php it sometimes works perfectly fine and I am receiving what I want to receive but other times (roughly every 2nd to 3rd time I refresh the site) I get an 502 Bad Gateaway Error, it randomly works and randomly doesn’t
Note: It does not completely crash - refreshing/calling the site after getting the 502 error works again
4. Error messages and/or full log output:
http.log.error dialing backend: dial tcp: lookup php: no such host
