This site can’t be reached

[Tvrdoglavi96]

Hello,

I have used your docker for past 2 years and did not have any issues.
I got a new PC and used online to setup your docker.
Everything went great but now i get the error This site can’t be reached....
I have checked my hosts file and everything is configured correctly.
Also i have run fixpermissions script but nothing changed....
OS is Ubuntu

Thanks in advance

Hi @Tvrdoglavi96! I'm Dosu and I’m helping the docker-magento team.

A common cause for this on Ubuntu with recent Docker Magento setups is the OpenSearch container failing to start, which can prevent the site from being accessible. This often happens if the env/opensearch.env file contains the line _JAVA_OPTIONS: -XX:UseSVE=0, which is incompatible with most non-ARM systems. Try removing or commenting out that line, then restart your containers. If the OpenSearch container was unhealthy, you may also want to increase the healthcheck retries in compose.healthcheck.yaml to 30 and follow the manual setup steps if you used the one-liner install script. More details are available here and here.

To reply, just mention @dosu.

No that is not the issue, opensearch is running normally.

Since OpenSearch is running, the most common causes for "This site can’t be reached" in docker-magento on Ubuntu are nginx/container issues, Docker networking, or firewall problems. Here’s a focused checklist:

• Make sure all containers are running and healthy: run bin/status or docker ps and check that app (nginx), phpfpm, and db are up.
• Confirm nginx is listening: run docker logs <nginx_container_name> and look for errors, especially about ports or SSL certificates.
• Check port mappings: nginx should expose port 80 (host) → 8000 (container) and 443 (host) → 8443 (container) (compose.yaml).
• On Linux, ensure your /etc/hosts and the extra_hosts section in compose.yaml are set up for host.docker.internal if needed (README.md).
• Try accessing both http://localhost and your configured domain (e.g., https://magento.test). If using a custom domain, confirm it points to 127.0.0.1 in /etc/hosts.
• Check for firewalls or security software blocking ports 80/443.
• Review nginx logs for errors: docker exec -it <nginx_container_name> cat /var/log/nginx/error.log.

If you spot anything unusual in the logs or container status, let me know the details and I can help interpret them.
