I have a brand new symfony 5 app in a docker container, on which I need to receive some webhook, thus using ngrok for tunneling. Thing is, ngrok keep sending me 502 errors, whereas the localhost access is doing fine. I'm kinda running out of ideas.
Curl using localhost:
$ curl -v http://localhost:4080/default
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 4080 (#0)
> GET /default HTTP/1.1
> Host: localhost:4080
> User-Agent: curl/7.52.1
> Accept: */*

Docker logs through ngrok (same as before):
payment_1 | [Web Server/PHP ] Jul 23 09:17:07 |INFO | PHP PHP message: Matched route "default". path="/usr/local/sbin/php-fpm" php="7.4.3"

Ngrok console (seems ok):
HTTP Requests
-------------
GET /default 200 OK
The docker container is lauched with symfony dev server via docker compose (docker-compose.yml extract):
version: '3'
services:
payment:
build: ./payment
command: sh -c "symfony server:stop && symfony server:start --port=4080"
environment:
APP_DEBUG: 1
VAR_DUMPER_SERVER: payment_dump:8000
volumes:
- "./payment:/app"
- "payment_composer:/root/composer"
expose:
- 4080
ports:
- "4080:4080"
And here is the Dockerfile:
FROM php:7.4-fpm-alpine
RUN apk add --no-cache \
git \
curl \
openssl \
ssmtp \
libzip-dev \
bash
RUN docker-php-ext-install -j$(nproc) \
pcntl \
zip
RUN apk add --no-cache icu-dev
RUN docker-php-ext-install intl
RUN wget https://get.symfony.com/cli/installer -O - | bash \
&& mv /root/.symfony/bin/symfony /usr/local/bin/symfony
RUN curl https://raw.githubusercontent.com/composer/getcomposer.org/d3e09029468023aa4e9dcd165e9b6f43df0a9999/web/installer | php -- --quiet \
&& mv composer.phar /usr/local/bin/composer
WORKDIR /app
ENV TZ="Europe/Paris"
ENV IS_DOCKER=1
I really don't understand what is going wrong. I have other container with similar configurations that seems to work fine. I've tried rebuilding the container, and various ngrok commands using *:4080 or http://127.0.0.1:4080, or some -host-header options. Also tried differents ports to no results. Result is of course the same in browser.
