502 Bad Gateway accesing from localhost

[ZJaume]

Info:

• Docker version ($ docker --version): 19.03.5-ce, 633a0ea838
• Laradock commit ($ git rev-parse HEAD): v9.2 d732318
• System info (Mac, PC, Linux): Linux
• System info disto/version: Arch Linux, kernel 5.4.2

Issue:

I'm trying to run laradock on local machine for development purposes. I'm using Caddy and Mysql and getting 502 or hang indefinitely when trying to access from the browser to 127.0.0.1. I also have tried with nginx but getting the same error. The strange thing is that exposed HTTP service is accessible outside localhost from other machines in the network, and my Laravel app is running fine from there.

Previous versions also didn't work (8.0 or 8.1)

Expected behavior:

Access to the http server with 127.0.0.1 address on the browser.

Reproduce:

Relevant Code:

0.0.0.0:80 {
    root /var/www/public
    fastcgi / php-fpm:9000 php {
        index index.php
    }

    rewrite {
        to {path} {path}/ /index.php?{query}
    }
    gzip
    browse
    log /var/log/caddy/access.log
    errors /var/log/caddy/error.log
    tls off
}

Sorry it was a problem with the VPN and iptables.

@ZJaume Please add the solution. I'm also having a similar issue.

It wasn't a docker issue itself, it was my VPN program that was messsing up iptables. Disabling the VPN solved the problem.

Thanks, @ZJaume. I'm having a problem without a VPN too.
