Certbot container does not work under kubernetes


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: staging.ishankhare.com

I ran this command: certbot certonly --noninteractive --agree-tos --staging --standalone -d staging.ishankhare.com -m me@ishankhare.com

It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator standalone, Installer None

Failed authorization procedure. staging.ishankhare.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://staging.ishankhare.com/.well-known/acme-challenge/tpumqbcDWudT7EBsgC7IvtSzZvMAuooQ3PmSPh9yng8: Timeout during connect (likely firewall problem)
- The following errors were reported by the server:

   Domain: staging.ishankhare.com
   Type:   connection
   Detail: Fetching
   Timeout during connect (likely firewall problem)

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A/AAAA record(s) for that domain
   contain(s) the right IP address. Additionally, please check that
   your computer has a publicly routable IP address and that no
   firewalls are preventing the server from communicating with the
   client. If you're using the webroot plugin, you should also verify
   that you are serving files from the webroot path you provided.
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.

My web server is (include version): standalone

The operating system my web server runs on is (include version): certbot/certbot docker container

My hosting provider, if applicable, is: gcloud

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no

What is weird is when i use the same container on a compute instance instead of kubernetes, it works perfectly and is able to verify my domain.
