API Error - docker-compose

API Error

The theme is not able to make contact with your Koken installation. Contact your host to see if they are blocking loopback connections.

proxy script

docker run -d -p 80:80 -p 443:443 -v /etc/nginx/certs:/etc/nginx/certs -v /var/run/docker.sock:/tmp/docker.sock:ro --name=proxy --restart=always jwilder/nginx-proxy

docker-compose.yml

koken:
  restart: always
  image: koken/koken-lemp
  container_name: koken.dev
  environment:
    - VIRTUAL_HOST=koken.dev
  volumes:
    - /home/vagrant/dpl/koken.dev/src/www:/usr/share/nginx/www
    - /home/vagrant/dpl/koken.dev/src/mysql/:/var/lib/mysql

someone know how fix it?

I can't get it to work either. My file looks like this:

koken:
  image: 'koken/koken-lemp'
  restart: always
  hostname: koken.example.com
  ports:
    - '8080:80'
  environment:
    - VIRTUAL_HOST=koken.example.com
  volumes:
    - './koken/data:/usr/share/nginx/www'
    - './koken/db:/var/lib/mysql'

Log in to the admin interface, download a theme and make sure to configure your site to use that theme.

[simonsmiley]

@5an1ty downloaded an additional theme, but I can't change the settings so that koken uses it. Do you also use a docker installation with port forwarding?

[Removed-5an]

Yes, installed it regularly, I recall having a similar theme error, opened up the admin interface on yourip/admin and modified the theme settings there.

You have to go to the site section, then click on the themes button at the bottom of the page and activate the theme you selected. (I tried the theme elementary)

Not sure what this env variable does, don't think I set it:
VIRTUAL_HOST=koken.example.com

[darklow]

I was able to fix this problem by modifying user_setup.php and adding following line:

define('LOOPBACK_HOST_HEADER', true);

For new build change file deploy/php/user_setup.php
For already deployed app file is under storage/configuration/

@darklow your advice don't solve my fix.... someone know how fix it?

thanks in advance...

If you're running in your own machine (i.e., not a public URL), your koken container needs to access your host.

Try adding:

web:
  extra_hosts:
    - koken.dev: 10.254.254.254

Replace 10.254.254.254 with your host's IP, but you might want to make an alias so it's always available independently from your network.

sudo ifconfig en0 alias 10.254.254.254 255.255.255.0 

Note: find your network interface, it might not be eth0.

This works for me.

I was facing the same issue while using the guide for Installing Koken to Digital Ocean droplet (via docker).
The installation page was hanging.
I added in user_setup.php:

define('LOOPBACK_HOST_HEADER', true);

under storage/configuration/

No need for any process restart, just refresh your browser. Your fresh new koken is there. It took me 1 week searching on web about this.

Thanks @darklow for sharing!

I had a similar issue even with define('LOOPBACK_HOST_HEADER', true); when I had another host terminate the SSL connection:

If you have this problem then you will probably see weird characters in the koken apache/nginx log: \x16\x03\x01\x02. The problem is that Koken determines the protocol it should use based on the web protocol used on the SSL-terminating proxy.
One option is to hack app/site/Koken.php with the solution shown here - which is not sustainable if you wonder why your koken does not run after an update.

I managed to get around this by enabling SSL in the Dockerfile:

# Enable SSL for loopback connections
RUN a2ensite default-ssl
RUN a2enmod ssl
RUN make-ssl-cert generate-default-snakeoil --force-overwrite 
EXPOSE 443

and exposing the koken host as an extra_hosts in the docker compose:

        extra_hosts:
          - ${DOMAIN}:127.0.0.1

Dockerfile and docker-compose.yml as a reference. If you are interested in my setup I have it here: https://github.com/pspoerri/docker-koken-letsencrypt (I still need to document and test it properly).

[darklow]

This is getting even more weird, under different server and different docker setup using docker-compose.yml in order to fix this issue I needed to do exact opposite - remove this line which I added to for previous setup to work define('LOOPBACK_HOST_HEADER', true);
