ddev playwright show-report --host=127.0.0.1 cannot connect

[tess-ten7]

After following the plugin installation instructions and validating that VNC is working, I cannot view the report using the following command:

ddev playwright show-report --host=127.0.0.1

The command output lists the following URL:

ddev playwright show-report --host=127.0.0.1

added 5 packages, and audited 6 packages in 274ms

found 0 vulnerabilities

  Serving HTML report at http://127.0.0.1:9323. Press Ctrl+C to quit.

This does not, however, show a report. Instead I get a "Cannot connect" message.

ddev describe suggests a different port, "9324", but the URL provided there results in a 'Bad Gateway' message.

Interesting, this was a docs-only change made in #93. You can bind to 0.0.0.0 for now. I wonder if ddev's router changed behaviour one way or another? What version do you have?

Still no luck on that either:

ddev playwright show-report --host=0.0.0.0

added 5 packages, and audited 6 packages in 244ms

found 0 vulnerabilities

  Serving HTML report at http://0.0.0.0:9323. Press Ctrl+C to quit.

Port 9323 never seems to be allocated and no connections on any loopback hostname fail to connect.

Ah ha! There are two problems:

• The instructions bind you to 127.0.0.1, which doesn't work for my version of DDEV for some reason.
• The Playwright output gives you a different port (9323) than DDEV prefers you use (9324 from ddev describe), and thus the documentation is a little confusing.

Excellent! 🙌 .

Not being able to bind to 127.0.0.1 is odd. The last time I hit that (a few years ago) it was actually a bug in macOS that you could workaround with a reboot.

The convention with Playwright is to bind http on 9323, and https on 9324. I don't know of any way to override the "Serving HTML report..." line, which is true, in that it is serving there (with https managed by the ddev router). Any ideas on how we could improve this?
