Not working: Installing Dockerized Wallabag on Traefik (+ Let's Encrypt Reverse Proxy)

[kromsam]

I am completely at a loss. I have been busy for almost the entire day to set up Wallabag using Traefik on my homeserver. I haven't been able to get Wallabag working at all, not even without Traefik. There are a lot's and issues concerning this topic on here, I used a lot of their tips but nothing worked. Therefore, I'll share my configuration and the steps I took, so that hopefully we can finally tackle this problem and be able to create a smooth and easy way to set up Wallabag on Docker.

Relevant parts of Docker Compose

I tried to follow these instructions: https://github.com/wallabag/docker . I added POPULATE_DATABASE=false which was suggested on multiple places, like here: #170.

version: '3'

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following command:

'/usr/bin/mysql_secure_installation'

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

Setting up the database

Now I run this command:
docker exec -t wallabag /var/www/wallabag/bin/console wallabag:install --env=prod --no-interaction

The output of which gives me only green checkmarks! I restart all containers:
docker restart wallabag wallabag_db wallabag_redis.

Let's look at the wallabag_db container logs:

And now at the wallabag container logs:

Conclusions

My browser still doesn't show anything when I go to yadayada.domain.tld, and the wallabag container doesn't seem to respond to these requests either. I have no idea what to do anymore! If anyone has an idea, I would love to hear it. All the best.

#Edit: I made a mistake setting up the DNS (which is hosted at Cloudflare). Now that that is fixed, the page yadayada.domain.tld gives me an Error 525 SSL Handshake failed.

The issue has been solved. There was an issue with Let's Encrypt and Cloudflare. I started using the dnsChallenge with Cloudflare as the provider.
