Network failed error

You can have some free domain here : https://www.freenom.com/ But I suggest you to reserve a $10/y domain on gandi or whatever

But that requires a custom DNS server? So other people won't be able to access unless they use the custom DNS server, right?

Yeah true

It's works with subdomain for us : http://dev.xx.yy

I meant Appwrite's main domain. It can be a subdomain, but the domain configured in the environment variables is Appwrite's main domain. Then there are custom domains for each project

the main point is we need new domain name for each project. right?

Depends of your implementation

As I see, it's works. You just need to add "S" to http on this config

http://139-59-64-251.nip.io/ => https://139-59-64-251.nip.io/

you have to buy a valid domain from any provider to use https://139-59-64-251.nip.io/ domain.

now I can use http://139-59-64-251.nip.io/ in my local server, if I put the project into the production I have to use this domain https://139-59-64-251.nip.io/ which I have to buy from a provider.

After that you'll have CORS errors <:appwritebow:824077772192088064>

Yehh

Here is the simplest solution

not really...

you don't need one. a domain for app is only required if you run into 3rd party cookie problems

are you talking about the ssl certificate?

yes

so Appwrite might be able to get an SSL certificate for you.

did you finish step 3 and 4?

No

I just confused, what I need to do

1. I want a domain name with SSL cortication

2. point it to your Appwrite server
3. Update the domain environment variables
4. Recreate the docker containers to deploy the environment variables change
5. Update your app to use the new domain via https for the appwrite endpoint

SSL != Domain. they are separate things and should be worked on separately. You need to get a domain. you can try using 139-59-64-251.nip.io.

step 2 is done already because 139-59-64-251.nip.io already points to your server. now, you're on step 3
