Error [ your connection is not private ] while accessing my website

When you configure your CNAME record to <user>.github.io , while accessing the website, i am getting this error.

Error Description

This is the complete error what i am getting while i am trying to access the custom domain

<CustomDomainWebsiteURL> normally uses encryption to protect your information. When Brave tried to connect to <CustomDomainWebsiteURL> this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be <CustomDomainWebsiteURL>, or a WiFi sign-in screen has interrupted the connection. Your information is still secure because Brave stopped the connection before any data was exchanged.

You cannot visit <CustomDomainWebsiteURL> right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

On inspection it is saying that the certification is not valid

It does support NS which Aternos needs for custom domains, so I want to cornfim.

How do I remove a registered domain on Open-domains?
I registered a domain, it was approved, but I only realised afterwards that I had the spelling incorrect.

Thank you,

Planning to support Vercel?

From the README:

We currently do not support Cloudflare (for NS), Netlify (for website) or Vercel (for websites).

This will hopefully be fixed soon.

Is there a plan to implement support for Vercel?
Or is there some workaround for Vercel users?

Add is-super.cool domain

Hi,

I'm a fan of your project 🤩 and I think the free subdomains are a great way to make projects more memorable 💡. I'd love to see the "is-super.cool" domain 🚀 added to Open Domains. I think it would make your project stand out and make it more appealing to users 💯.

I think the "is-super.cool" domain is a fun and playful way to add personality to a domain name ✨. It's also short and easy to remember 📝. I believe that it would be a great addition to your project and would help to make it more unique and memorable 😉.

Thanks for your time!

Support for other than git pages or cloudflare pages

Having issues trying to "change" the domain of my subdomain

Tried renaming the files (for example example.is-cool.dev.json to example.is-not-a.dev.json), but no avail.
I'm not sure If I have to delete the files, and then add the new ones.

How can I cancel my registration since I changed my mind?

Hello.

I recently requested a domain: villenmarx.is-cool.dev.json here for the site: villenmarx.github.io. So, but... now, I don't want opendomain anymore. I think it's better to leave it standardized by .github.io. How can I cancel my registration since I changed my mind?

Veryfying Domain

When I try to add my domain name as a custom domain to the github pages section, it asks me to verify the domain.
What am I supposed to do?
Can you guide me through the process of linking and setting up a domain to gothub pages?
(I dont know about A AAAA CNAME TXT records etc)

Validation errors

Hey.
This error is starting to get on my nerves, and, even after adding the CNAME record for my domain, aleph.is-local.org, Github Pages still asks for verification.

Is this happening to anyone else? If so, are there any other options besides Github Pages that I can use?
Or am I doing something wrong?

Wildcard domains do not work

Hi,

Everything works except wildcard domains.
Can you please help check if I did it right?
Thanks.

PTR record?

Hey team, thanks for this great project.

I note that a critical step in having a vaguely reliable self-hosted mail server is confirming a reverse DNS PTR record exists to resolve your hostname from your IP address.

Is this possible, by some magic I'm unaware of, with open-domains subdomains? If i was for example andrew.is-not-a.dev , could i host my own email server and have a reverse DNS PTR record so my mail isn't mostly just marked as spam immediately no matter what else i do?

thanks kindly
