keendns Error 302 when receiving an ssl certificate for a Level 4 domain name

[Stus Game]

• I am trying to obtain ssl certificate with the command below

ip http ssl acme get app.domain.keenetic.link

but it doesn't work. I'm only getting the

obtaining certificate for domain "app.domain.keenetic.link" is started. 

message.

• Log:

You don't need to obtain level4 certificate, keendns level3 is wildcard certificate and it is valid for any subdomains

Then keendns won't help you, it can proxy http(s) requests, but won't supply you with certificate to be used outside router's web server.

But how can I start an https server now? I think I need to specify the certificate file, which means it should be on my computer.

Explain what is your goal.

May be keendns not right service you are looking for. It won't give you any certificates to be used outside webserver in router.

I want to get a domain name for an https server. This way seemed like a good free solution. And yes, the server must use https because KeenDNS is only used for development. Later I will buy a domain name and transfer my server to a web hosting without rewriting http to an https server.

Google Translate:

I saw while browsing the device files, are these certificates private key or public key?
