Listen address in config

[vinceh121]

These changes allow users to configure the server's listen address.
0.0.0.0 is still the default.

Thanks @vinceh121

Can you please sign the DCO? Details at:

(Since it's a minor change, I can merge without DCO, but it would be good if you do sign it; thanks)

Thanks @vinceh121

Would be thrilled to know if you use the project. Please do share a link when you can.

I am using LibreCaptcha in my GMCServer project for account registration, works like a charm!

Great! From a quick search in that repo, it seems like you are using text CAPTCHA? Have you created your own custom text CAPTCHAs?

[vinceh121]

I didn't create a custom CAPTCHA provider if that's what you're asking, although my implementation works with any type of CAPTCHA, as long as they don't require custom properties.

[hrj]

Oh ok.

My question was wrong; I saw input-type=text in there and wrongly thought that the challenge type was text. And since we haven't implemented text captchas yet, I thought you might have implemented a custom one. 🤦🏽
