pagekite.py [flying] DynDNS updates may be incomplete, will retry - tunneling

Question

I am trying to make my localhost:80 available on the internet using pagekite with config at ~/.pagekite.rc:
## NOTE: This file may be rewritten/reordered by pagekite.py.
#
##[ Default kite and account details ]##
kitename = myemail#gmail.com
kitesecret = my_kite_secret
##[ Front-end settings: use pagekite.net defaults ]##
defaults
##[ Back-end service examples ... ]##
#
service_on = https:asldkjdk39090.pagekite.me:localhost:80:my_kite_secret
END
I run pagekite:
# pagekite.py
>>> Hello! This is pagekite.py v0.5.9.3. [CTRL+C = Stop]

~<> Flying localhost:80 as https://asldkjdk39090.pagekite.me/
Trying localhost:80 as https://asldkjdk39090.pagekite.me/
<< pagekite.py [flying] DynDNS updates may be incomplete, will retry...
Then I request https://asldkjdk39090.pagekite.me/ and it gives an error:
$ curl https://asldkjdk39090.pagekite.me/
curl: (6) Could not resolve host: asldkjdk39090.pagekite.me
I don't clearly understand why it's not working and how to fix it. I expect that pagekite pass request to my localhost:80 when I request https://asldkjdk39090.pagekite.me/ but it doesn't.
Update
With this config it's working:
## NOTE: This file may be rewritten/reordered by pagekite.py.
#
##[ Default kite and account details ]##
kitename = my_kite_name
kitesecret = my_kite_secret
##[ Front-end settings: use pagekite.net defaults ]##
defaults
##[ Back-end service examples ... ]##
#
service_on = http:my_kite_name.pagekite.me:localhost:80:my_kite_secret
END
Where my_kite_name is the name I created on settings page.
Then curl https://my_kite_name.pagekite.me/ redirects properly to my localhost
So it's working for pre-created names and not working for a random name like asldkjdk39090 which I want to use as a subdomain on the fly without registering it on the settings page.

Answer 1

On-the-fly subdomains aren't supported by pagekite.net.
You always have to pre-register, either using the website or the built-in registration tool in pagekite.py itself. Unfortunately, on some modern distros the built-in pagekite.py registration is currently broken because our API server is obsolete and modern versions of OpenSSL refuse to connect to it.
We are working on fixing that, obviously, but it will take some time because of dependencies.
