If https://v.je will not open, first identify whether Docker failed to start, the browser cannot reach the web service, or the browser reached the site but rejected its certificate. Those are different problems, and the reports about this setup do not establish one universal cause or a confirmed fix.
What v.je should do
v.je is the local site address for a Docker-based PHP development environment. The documented setup includes NGINX, MariaDB, PHP, Composer, and PHPUnit. The book’s setup instructions say to start the Docker Compose environment and then visit v.je over HTTPS. Default site files belong in websites/default/public; directories under websites can map to subdomains. These instructions describe the intended setup, not whether a particular computer’s containers or browser connection are working. Project and book information.
First, identify the failure stage
- Record the exact browser message. A certificate warning,
ERR_CONNECTION_REFUSED, and a page that never loads are not interchangeable. Note whether the browser names a certificate error or says the connection was refused. - Check Docker Compose status and output. Determine whether the services are running or whether startup stopped with an error. Look for which service failed and capture its relevant log output.
- Check the logs around the failure. A database or certificate-update error may indicate an earlier failure than the browser message. Keep the full sequence and timing rather than treating the last visible symptom as the root cause.
If a container fails to start
Start with the Compose output and logs for the failing service. In the July 2026 discussion, users reported a MySQL message about being unable to get a private key and a Docker Desktop update-certificate error describing an invalid or uninitialized ZIP object. Those reports are evidence of distinct failures in that setup, not proof that either one explains every v.je issue or a verified repair.

If the browser says ERR_CONNECTION_REFUSED
This message is different from a certificate warning: the browser is not reporting a certificate it reached and rejected. Check whether the web service is running and listening on the ports configured by the Compose setup, and whether the v.je hostname resolves to the local environment as expected. Review the web service logs and the actual Compose configuration; the available reports do not provide a confirmed port, hostname change, or machine-specific fix.
A Windows user previously reported that containers appeared to be running while v.je remained unreachable, but that older report does not diagnose another computer’s setup. The Stack Overflow question.

If the browser reports a certificate error
A certificate error means the browser reached a certificate check, so investigate the certificate path and validity separately from a refused connection. The July 2026 discussion included net::ERR_CERT_DATE_INVALID, but it did not establish a successful fix for the original poster.

What the reports do—and do not—confirm
A July 2026 thread about opening v.je after setting up the book’s Docker environment described an initial browser security warning, then failures in Chrome, Edge, and Firefox, and later the distinct errors above. Participants suggested generating local certificates and trying a repository, but the original poster said the problem remained unsolved. Neither suggestion should be treated as a confirmed remedy. The book’s setup context.
Without the affected computer’s operating system, Docker and Compose versions, Compose configuration, web-service health and listening status, and complete current logs, the cause cannot be narrowed down reliably. If asking for help, include those details alongside the exact browser error and the sequence in which it appeared.
