Laradock Traefik gateway timeout - laravel

Question

I am deploying a Laravel app with Laradock and Traefik as a reverse proxy.
When I hit the mydomain.com it shows an error message
Gateway timed out
When I inspect
docker network inspect traefik_proxy
I get the following:
"Containers": {
"100bbf77ba58214b286d892245fd2008458ed0b266f67e9f3bb7a68589229f7a": {

},
That means that Traefik is apparently aware of those containers and they are in the same network.
Here is my docker-compose.yml in the Nginx part:
version: '3.5'

frontend:
driver: ${NETWORKS_DRIVER}

external:

Any ideas on what to check for , or any workaround?
How do I fix it?
Troubleshooting for my future self (workedaround-solved)
This error is shown, whenever I rebuild a container, for example, the php-worker when I added the wktohtmltopdf library or the php zip extension:
docker build php-worker
Follow the two steps:
Inside the laradock directory, restart the containers:
docker-compose restart
Inside the traefik directory, execute
docker-compose restart at least twice or even thrice and wait patiently to reload
The application should finally be up and running
